Particle accelerator
A particle accelerator is a device that uses electromagnetic fields to accelerate charged particles to high speeds and contain them in well-defined beams. They can be used for purposes like radiotherapy, ion implantation, and industrial and biomedical research. The largest particle accelerators in the world are the RHIC, the LHC at CERN, and the Tevatron, which are used for experimental particle physics research. Particle accelerators can be divided into low-energy machines like cathode ray tubes and X-ray generators, and high-energy machines capable of nuclear reactions like the LHC, which smashes particles together at high speeds to study the origins of the universe.
CHARGE PARTICLE ACCELERATORCharge particle accelerator
A particle accelerator is a device that increases the kinetic energy of electrically charged particles through the use of electric and magnetic fields. The cyclotron, invented in 1931, is an early type of particle accelerator that uses a high frequency oscillator to accelerate positively charged particles in a spiral path between two "D-shaped" electrodes placed in a strong magnetic field. As the particles accelerate, they travel in larger circular paths until they exit and can be used for nuclear reaction experiments or medical treatments like cancer therapy.

Presentation of my research of graduated
I tried to describe that "how the particle
Accelerators work?". I spoke about all types of accelerators from the past to the present.
The electron synchrotron
A synchrotron uses a cyclic particle accelerator to accelerate charged particles to very high energies using alternating electric and magnetic fields. The first electron synchrotron was constructed in 1945 by Edwin McMillan at the University of California, designed for energies between 320-350 MeV. A synchrotron consists of an electron gun, linear accelerator, booster ring, storage ring, beamline, and end station to produce and direct beams of synchrotron light for applications in spectroscopy, crystallography, medical imaging, and cancer therapy.
The Cyclotron
The cyclotron was invented by Leo Szilard in the 1920s and was a particle accelerator that influenced scientific research. It works by accelerating charged particles in a spiral path within magnetic fields, gaining more speed and energy with each turn. Cyclotrons were important for producing radioactive isotopes used in medical imaging technologies like PET and for experiments in nuclear and particle physics. They had advantages over previous accelerators but also limitations in the size of particles they could accelerate. Cyclotrons played a key role in scientific discoveries and the development of nuclear medicine.
Synchrotron
The document discusses synchrotrons, which are particle accelerators that produce very bright light for research. It describes how synchrotrons work, with electrons being emitted and accelerated through components like an electron gun, linear accelerator, booster ring, and storage ring. This produces intense electromagnetic waves called synchrotron light. Synchrotron light is much brighter than standard X-rays and allows scientists to observe molecular interactions. The document outlines some of the many applications of synchrotrons, such as in materials engineering, medical imaging and therapy, environmental research, and forensics.
Synchrotron radiation
Synchrotron radiation is electromagnetic radiation emitted when charged particles travel along a curved path at relativistic speeds. The document discusses the historical background, design, components, and detection of synchrotron radiation. It also outlines the properties, advantages, and applications of synchrotron radiation, which include life sciences research, materials science, medical imaging, and cancer treatment. Synchrotron facilities around the world provide intense beams of synchrotron light for scientific experiments.

Chap1 intro to-accelerators_final
This document provides an overview of particle accelerators. It notes that there are over 30,000 accelerators worldwide used for research, medicine, and industry. Accelerators are used to produce beams of particles like electrons and ions that act as probes for scientific research. Examples of applications mentioned include medical isotopes and radiation therapy, material modification and analysis using synchrotron light sources, and particle physics research using large facilities like CERN. The document aims to give the reader a broad introduction to the field of accelerators and their diverse applications.
Cyclotron
This document describes the working of a cyclotron particle accelerator. It explains that a cyclotron uses a magnetic field to curve the path of charged particles into a circular orbit, while an alternating electric field accelerates the particles at each half orbit. As the particles accelerate, they travel along spiraling paths of increasing radius. The document provides details on the construction of a cyclotron, including its dees and vacuum chamber between magnets. It also gives the mathematical expression for the cyclotron frequency that determines the electric field frequency needed for resonance acceleration. Limitations of the cyclotron are that particle mass may change at high speeds and it is difficult to accelerate low-mass particles like electrons.
Cyclotron
- Cyclotrons use magnetic and electric fields to accelerate charged particles in a circular path, increasing their energy each time they pass through the accelerating field. Ernest Lawrence invented the cyclotron in the 1930s.
- Cyclotrons consist of two semicircular electrodes called dees placed between the poles of a magnet. Charged particles are accelerated as they spiral between the dees due to alternating electric fields.
- Cyclotrons are used to accelerate protons and ions for applications such as nuclear physics experiments and particle therapy for cancer treatment. They can also produce short-lived radioactive isotopes used in PET imaging. However, maintaining uniform magnetic fields over large areas is challenging for cyclotrons.
Cyclotron
The document is a student project report on cyclotrons. It includes an introduction describing cyclotrons, their principles and construction which involve two dees positioned between magnet poles that accelerate charged particles in a spiral path. The report further describes the theory behind how cyclotrons work using magnetic and electric fields to accelerate particles. It also discusses the limitations and uses of cyclotrons such as studying nuclear reactions and producing neutrons.
Synchrotron
Synchrotron radiation is produced when electrons are accelerated radially in a storage ring. Electrons are injected into the storage ring using a linear accelerator and booster ring to achieve energies of 2-8 GeV. Magnets such as dipoles, quadrupoles and sextupoles are used to focus and steer the electron beam. Insertion devices like wigglers and undulators produce intense beams of synchrotron radiation. Beamlines transport this radiation from the storage ring to experimental end stations, where samples are analyzed using techniques like diffraction and spectroscopy.
Linear Accelerators
Linear accelerators (linacs) are used to generate high energy x-ray and electron beams for radiation therapy. A linac consists of an electron gun, radiofrequency power source, accelerating waveguide, beam transport system, and treatment head. Electrons are generated and accelerated to megavoltage energies using microwave fields in the waveguide. The accelerated electron beam is transported and bent using magnets to strike a target and produce x-rays, or exit directly as an electron beam. The treatment head houses the target, flattening filter, collimators, and monitors to shape the beam for patient treatment. Modern linacs provide flexible photon and electron beams with variable energies for radiation therapy.
PET Cyclotron
Cyclotrons are particle accelerators that use magnetic and electric fields to accelerate charged particles in a circular path. They are commonly used to produce short-lived radionuclides for positron emission tomography by bombarding target materials with protons or deuterons. Key components of a cyclotron include ion sources, dees, magnetic fields, radiofrequency systems, and targets.
Cyclotron
The document summarizes the cyclotron, which accelerates charged particles. It was invented in 1934 by Lawrence and Livingston. A cyclotron uses a magnetic field to bend charged particles into a circular path between two "dees" where an alternating electric field accelerates the particles on each half-circle. As the particles' velocity and radius increase with each pass between the dees, their kinetic energy also increases until they exit the cyclotron. The cyclotron is still used today as the first stage of some large particle accelerators to produce very high energy particles for nuclear physics experiments requiring high-energy collisions.
Cyclotron (1)
Cyclotrons accelerate charged particles using oscillating electric fields generated between hollow metal chambers called dees. A positive ion is placed between the dees and accelerated toward the first dee when it is negatively charged. It follows a semicircular path due to a strong magnetic field until the dee polarities are reversed, accelerating it toward the second dee and to higher energies with each pass through the oscillating field. Cyclotrons can be used to accelerate ion beams for nuclear physics experiments and cancer treatment through proton therapy.

The document discusses cyclotrons, which are particle accelerators that use oscillating electric fields and strong magnetic fields to accelerate charged particles in a spiral path.

sBetatron
The document summarizes the working principles of a betatron, which is a device that uses changing magnetic fields to accelerate electrons in a circular path. It describes how Donald Kerst constructed the first betatron in 1941 at the University of Illinois and successfully accelerated electrons, producing x-rays. The betatron operates by injecting electrons into a doughnut-shaped vacuum chamber located between the poles of an electromagnet. As the alternating magnetic field increases over time, it induces an electric field that accelerates the electrons in their circular orbit to high energies without changing their radius, following the betatron condition of ΦB = 2πr2B.
Nuclear Power
This document discusses nuclear energy and radioactivity. It explains that atoms are held together by strong and electromagnetic forces, and that most elements are stable when they have equal numbers of protons and neutrons. However, additional neutrons can make atoms unstable and radioactive. Radioactive atoms undergo decay, emitting particles or rays and transforming into lighter elements. Nuclear fission is the splitting of heavy nuclei like uranium-235 by neutrons, releasing energy. This energy can be harnessed in nuclear reactors to generate electricity through heating water to create steam. Nuclear fusion also releases energy as hydrogen fuses to form helium in stars like the Sun.
Betatron ppt
A betatron is a device that accelerates electrons using an expanding magnetic field within a doughnut-shaped vacuum chamber. Electrons are injected into the chamber and accelerated as the magnetic field strength increases over time. This increasing magnetic flux induces an electric field that increases the electrons' energy, allowing them to gain extremely high speeds. The betatron condition requires that the rate of change of magnetic flux through the circular orbit equals 2π times the radius squared times the rate of change of the magnetic field, in order to maintain the electrons' constant orbital radius as they accelerate.

Particle beam – proton,neutron & heavy ion therapy
particle therapy is advanced external beam therapy used to treat cancer , which uses beams of protons or other charged particles such as helium, carbon or other ions instead of photons. charged particles have different depth-dose distributions compared to photons. They deposit most of their energy in the last final millimeters of their trajectory (when their speed slows). This results in a sharp and localized peak of dose, known as the Bragg peak.
Higgs Boson
The document discusses the history of particle physics and the development of the Standard Model of particle physics. It describes how particles like electrons, protons, neutrons were discovered and how the atomic model evolved. Experiments at particle accelerators revealed more fundamental particles that were grouped into families and the three quark model was developed. The Higgs mechanism was proposed to explain how fundamental particles acquire mass through interacting with the hypothesized Higgs field. The Large Hadron Collider was built at CERN to search for the predicted but not yet observed Higgs boson and potentially discover signs of new physics like supersymmetry.

The cyclotron accelerates charged particles using oscillating electric and static magnetic fields. Particles are injected into the center and accelerated along a spiral path between hollow metal electrodes called dees. The magnetic field causes particles to travel in a circular orbit while the alternating voltage between the dees, matched to the cyclotron resonance frequency, accelerates the particles with each orbit. This allows particles to reach high energies using relatively low voltages. Cyclotrons are used to produce short-lived medical radioisotopes like fluorine-18 for positron emission tomography imaging of brain and cancer cells.

Nuclear magnetic resonance partial lecture notes
1. Nuclear Magnetic Resonance (NMR) spectroscopy utilizes the magnetic properties of certain atomic nuclei to determine the structure of organic molecules.
2. NMR works by applying a strong magnetic field which causes the nuclei of atoms like 1H, 13C, and 19F to align and absorb electromagnetic radiation at characteristic frequencies.
3. The frequency of absorption, known as the chemical shift, depends on the magnetic field strength and the electron density around the nucleus, providing information about the molecular structure.
Interaction of Photons and Charged Particles with Matter.pptx
This document discusses the characteristics and types of interactions that occur when photons and charged particles interact with matter. There are three key points:
1) Total energy is conserved in all interactions, though kinetic energy is only conserved in elastic interactions. Interactions can be classified as elastic or inelastic.
2) Charged particles like electrons and protons directly ionize atoms by ejecting electrons, while uncharged particles like neutrons and photons indirectly ionize by setting charged particles in motion first.
3) The linear energy transfer (LET) describes the average energy lost per unit distance by an ionizing particle, and is used to calculate particle range in a medium. Higher atomic number materials cause more scattering.

Maas spectroscopy
Mass spectroscopy (MS) is an analytical technique that ionizes chemical species and sorts the ions based on their mass to charge ratio.
Cyclotron
The cyclotron is a device that accelerates charged particles using electric and magnetic fields without the need for high voltages. It works by subjecting charged particles like protons to alternating electric fields while maintaining their circular path using a constant perpendicular magnetic field. This causes the particles to gain kinetic energy and travel in an increasingly larger circular trajectory with each pass through the electric field until they exit the cyclotron with energies in the MeV range, useful for applications like medical isotope production and cancer treatment.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
