The document discusses the front-end electronics (FEE) developed for the timing RPCs used in the HADES experiment. The FEE consists of daughter boards (DBOs) connected to the RPC cells that amplify and digitize signals, and mother boards (MBOs) that interface between the DBOs and data acquisition system. The FEE achieves a time resolution of less than 17 ps using a charge-to-width algorithm to encode timing and charge information. Testing shows the FEE performs well and could be adapted for use in the TRASGO detector with some modifications to reduce power consumption.

Spectral Analysis at the Limit - Applications in Radio Astronomy
Spektralanalyse am technologischen Limit: Anwendungen in der Radioastronomie
Wo Prozessoren in ihrer Leistungsfähigkeit nicht mehr ausreichen, wird programmierbare Logik in Form von FPGAs (Field Programmable Gate Arrays) eingesetzt. Hunderte von Rechenoperationen können damit innert Nanosekunden erledigt werden. Diese Technologie eignet sich vorzüglich für die Echtzeit-Spektralanalyse von Signalen.
Typische Anwendungen finden sich in der Radioastronomie oder der Atmosphärenphysik. Typisch sind die enormen Abtastraten von mehreren Giga-Samples pro Sekunde bei Wandler-Auflösungen von ³ 10 Bit, Signal-Bandbreiten von > 1 GHz, aufgelöst in ³ 16'384 Kanälen. Die Leistungsgrenze wird in diesen Bereichen stetig nach oben geschoben.
Mit dem präsentierten Projekt wurde ein neuer Meilenstein punkto Funktionalität und Verarbeitungsgeschwindigkeit gesetzt. So ist das realisierte Spektrometer 1- oder 2-kanalig konfigurierbar, in der 2-kanaligen Version können beispielsweise die Summen- und Differenzspektren gerechnet werden, oder das Kreuzleistungs-Spektrum. Anstelle der "normalen" Fast Fourier Transform (FFT) wurde eine digitale Filterbank implementiert.
Im Vortrag werden aktuelle und künftige Anwendungen im Bereich der Radioastronomie vorgestellt. Es sind Anlagen und Projekte, die weltweit in Betrieb sind oder in Planung stehen. Messresultate zeigen die enorme Leistungsfähigkeit, aber auch die Grenzen der digitalen Spektralanalyse.

PIERS2018 Korogodin Naive beamforming for multi-element antenna GNSS receiver
This document presents a naive beamforming approach for multi-element GNSS antennas that does not require antenna calibration or attitude estimation. It uses a multi-input correlator with difference phase locking loops between elements to directly measure phase differences. Experimental results show around 7-8dB of SNR gain and improved pseudorange and pseudophase accuracy. While it increases correlator complexity, this naive approach provides beamforming benefits without extensive antenna modeling. The approach provides a simple interface between the antenna and receiver and could be combined with conventional beamforming techniques.

RM03D-3_DCOBISC_06_07_09_Final
This document describes a technique for digitally calibrating the current of a digitally controlled oscillator (DCO) to optimize its phase noise performance across process and temperature variations. The phase error (PHE) signal from a digital PLL is digitized and used to estimate the DCO's phase noise. By adjusting the DCO current digitally based on the estimated phase noise, the optimum operating point with minimum phase noise can be identified. Measurement results on a 90nm CMOS chip demonstrate good correlation between the estimated and measured DCO phase noise, validating the digital calibration approach.

Introduction to pll
1. The document introduces phase locked loops (PLLs), which are electronic circuits that lock the phase of the output signal to the phase of the input signal.
2. A basic PLL system consists of a phase detector that detects the phase difference between the input and output signals, a low pass filter, and a voltage controlled oscillator whose frequency is adjusted based on the output of the filter to reduce the phase difference.
3. Modern PLLs often use a phase/frequency detector and a charge pump instead of just a phase detector, which allows the loop to lock faster and be more stable. Charge pump PLLs work by using the phase/frequency detector to control switches that charge or discharge a capacitor, producing the control voltage

Pll
The PLL consists of a phase detector, low pass filter, error amplifier, and voltage controlled oscillator (VCO). The phase detector compares the input signal frequency to the VCO output frequency and generates an error voltage if they differ. This error voltage is filtered and amplified to control the VCO frequency, shifting it toward the input signal frequency, forming a feedback loop that locks the VCO frequency to the input signal frequency.

Jj Taboada C Rays Climate
This document discusses the relationship between cosmic rays, solar activity, and climate/weather patterns. It begins by outlining how solar wind modulates cosmic rays, which influence cloud formation by acting as cloud condensation nuclei. Studies of Forbush decreases have provided evidence this mechanism works in the real atmosphere. The author then discusses how cosmic ray flux variations from our galactic position may have influenced past climate changes. Finally, the document analyzes correlations between solar activity and climate variability patterns like the NAO and weather types in Galicia, Spain. The overall evidence suggests solar activity modulates cosmic rays in ways that influence global and regional climate and weather patterns.
T Kurtukian Midas
The document presents work on the MIDAS project which aims to identify particle masses using multiple sampling. It outlines results from initial MATLAB simulations showing electrons can be distinguished from muons and protons below 500 MeV. A Geant4 simulation using the SETA environment was also developed to model the TRASGO detector in more detail. Further simulations are needed but combining velocity, chi-squared values with additional information like timing may allow ambiguous particles to be discriminated.
M Morales Sealed Rpcs
The document discusses the development of sealed resistive plate chambers (sRPCs) as a more flexible alternative to gas ionization detectors that do not require a gas system. Several prototype sRPCs were constructed and two were tested with radioactive sources, though two failed on the first day with little response. Signals from the functioning chambers increased over time, and high voltage had to be decreased to avoid streamers but with reduced gain. Further testing is needed to evaluate resolution, efficiency, isolation, and alternative gas mixtures to better understand aging effects in sRPCs.
G Kornakov E A Smultivariate Analysis
The document summarizes a simulation of extensive air showers (EAS) using the AIRES code. Key points:
1) Simulations were run for primaries of protons, carbon, iron, and gamma rays with energies of 1015 eV in the "knee" region to study EAS characteristics.
2) Variables like energy, arrival time, production height, and identity of secondaries were recorded. Results showed differences in lateral distribution and time profiles between primaries.
3) Further analysis of observables like particle counts, arrival times, and azimuthal/zenith angles at different distances from the core is planned to better understand correlations with primary properties. Multivariate analysis techniques may help reveal hidden

The document then discusses how this proposed mechanism may influence climate through impacts on cloud radiative forcing. It analyzes links between various climate patterns like the North Atlantic Oscillation and weather types with rainfall and temperature in Galicia, Spain, and how these correlations have changed over time with solar activity levels.
D Gonzalez Diaz Optimization Mstip Rp Cs
This document discusses signal coupling in multi-conductor highly inhomogeneous HF environments like multi-strip timing RPC detectors. It summarizes simulations and measurements of cross-talk and time resolution in multi-strip RPC detectors of various lengths from 20cm to 100cm.
