PHENIX @ RHIC

• 11 detector sub-systems

• 2 Arm central spectrometers:

  • |h|< 0.35, Df = p/2 (e, g, hadrons)
  • Open geometry axial field

• 2 forward spectrometers (2nd year)

  • 1.2 < |h|< 2.5, Df = 2p (muons)
  • Radial magnetic field

• 3 global (inner) detectors: trigger, centrality

• Designed to measure rare probes:

• + high rate capability & granularity

• + good mass resolution and PID

• - limited acceptance
