Basic Requirements

The envisaged physical program (see TPR) of PANDA requires a

  • hermetic detector with nearly 4pi solid angle coverage
  • concurrent detection of lepton pairs
  • good kaon identification from very low energies up to a few GeV/c
  • detection of low energy photons
  • muon detection capability
  • higly segmented low energy threshold electromagnetic calorimeter
  • (second) vertex recognition
  • radiation hardness
 
Added:

  • good PID above particle momenta of 0.5 GeV/c at all angles
