Institute of research into the fundamental laws of the Universe

Investigation means

• Proton-antiproton collider Tevatron (about 2 TeV in centre-of-mass)
• Particles identification from several detectors
• Physics processes and detectors response simulation softwares
• Data analysis software

 Technical description

Different detectors with cylindrical symmetry, organized in layers around the beam axis:

• liquid argon calorimeter;
• - tracking detectors in a 2 Teslas magnetic field from a superconducting coil;
• - muons detectors.

New elements installed between 1996 and 2001 for the Run II upgrade:

• superconducting coil
• new tracking detectors ( Fiber tracker, Silicon microstrip vertex detector)
• new read-out electronics for the calorimeter
• New forward muon system

Spécificities:

• The calorimeter partly made of depleted uranium plates in a liquid argon bath.
• Muon spectrometer using an iron toroidal magnet
