2. WHAT IS LARGE HADRON
COLLIDER(LHC)?

3. The Large Hadron Collider
(LHC) is the world’s largest and
most powerful particle
accelerator. It first started up
on 10 September 2008, and
remains the latest addition to
CERN’s by “PETER HIGGS”
The LHC consists of a
27-kilometre ring of
superconducting magnets with
a number of accelerating
structures to boost the energy
of the particles along the way.

5. WHAT IS THE MAIN PURPOSE OF THE LHC?
The aim of the LHC is to allow physicists to test the
predictions of different theories of particle physics,
including measuring the properties of the Higgs boson
and searching for the large family of new particles
predicted by supersymmetric theories, as well as
other unsolved questions of physics

6. WHAT DOES A
PARTICLE DO?
A particle accelerator is a machine that accelerates elementary particles, such as
electrons or protons, to very high energies. On a basic level, particle accelerators
produce beams of charged particles that can be used for a variety of research purposes.
... Circular accelerators propel particles around a circular track.

9. WHAT IS THE MASS SPEED OF THE HIGG BOSON?
On 4 July 2012, the ATLAS and CMS experiments at
CERN's Large Hadron Collider announced they had each
observed a new particle in the mass region around 126
GeV. This particle is consistent with the Higgs
boson predicted by the Standard Mode

11. WHAT IS THE SPEED OF THE PROTON IN LHC?
I've read in numerous places that the Large Hadron Collider
is capable of accelerating protons at 0.999999991 c, which
mathematically works out to being 3 meters per
second slower than the speed of light

12. HOW DO YOU ACCELRAET THE PARTICLE ?
Their job is to speed up and increase the
energy of a beam of particles by generating
electric fields that accelerate the particles,
and magnetic fields that steer and focus
them. ... The Large Hadron Collider (LHC)
accelerates and collides protons, and also
heavy lead ions.

15. From here, the beams inside the LHC are made to
collide at four locations around the accelerator ring,
corresponding to the positions of four particle
detectors – ATLAS, ALICE , CMS and LHCb.

17. ALICE

18. CMS(compact muon solenoid)

19. LHCB

20. ATLAS :
One of two purpose detector. Atlas will be used to look
signs of new physics, including the origins of mass and extra
dimensions
ALICE :
Hunt for higgs boson and look for clues to the nature of
clark matter.
CMS :
Alice is studying a “fluid” form of matter called quark-
glucon plasma that exited shortly after the big-bang
LHC :
Equal amount of matter and antimatter were created in
the Big-Bang . LCHB will try to investigate . What happened to
the missing antimatter

21. APPLICATIONS OF LHC
• Cancer therapy
• Manufacturing processes
• Medical instrumentation
• Industrial imaging
• The world wide web
• Patter recognition

22. MERITS:
• Development in quantum mechanics
• Searching for the source of dark matter .searching for
the causing of matter – antimatter asymmetry in the
universe
• Measuring the size and structure of the proton .
• To study the behavior of cosmic rays in atmosphere .

23. DEMERITS:
• The Large Hadron Collider took total cost of about
$4.75 billion .
• Its life time is only 10 year after that we need to find
a new collider to construct.
• 120megawatts – about as much as all of the homes in
the neighboring swiss canton of Geneva

25. conclusion
The LHC is now in its final stage of installation and
commissioning .
A beam has already been extracted from the SPC with
the parameter needed to achieve design luminosity and
has been transported along the 2.6 KM tunnel TI8 to
the LHC injection point
