LHC LARGE HADRON COLLIDER. World’s largest and highest-energy particle accelerator. Built by the European Organization for Nuclear Research(CERN). To study high-energy physics & large family of new particles predicted by supersymmetry. What is HADRON ?.
Approx. 96 tonnes of liquid helium needed to keep the magnets at the operating temperature of 1.9 K(-271.25C).
ATLAS consists of a series of concentric cylinders around the interaction point where the proton beams from LHC collide.
CMS is designed as a general purpose detector, capable of studying different aspects of proton collision at 14 TeV.
It is optimized to study heavy ion collisions. Pb nuclei collisions will be studied at a center of mass energy of 2.76 TeV per nucleon.
4. Photon Spectrometer: made of lead tungstate crystals, it measures the temperature of collision of high energy photons emerging out after striking the crystal.
5. Muon spectrometer: measures pairs of muons, in particular those coming from the decay of upsilon & psi particles.
6. Electro-magnetic Calorimeter: it adds to the high momentum particle measurement capability of ALICE.
7. High Momentum Particle Identification Detector: it determines the speed of particles beyond the momentum range available through energy loss in ITS & TPC. Its range is upto 5 GeV. It is world’s largest caesium iodide detector.
CERN scientists estimates that if the Standard Model is correct, a single Higgs boson may be produced every few hours and may take 2 to 3 years to collect enough data to discover it precisely. Similarly, it may take one year or more to draw meaningful conclusion concerning supersymmetric particles.
