  The magnetic field in this area is in the order of 0.2Tesla, one has a few options in orienting the phototubes, but then magnetic shielding might be required nevertheless.

    Motivation and Kinematics

Particle ID cannot rely on strangeness conservation as strangeness is fed from heavier flavours, in particular charme, and the CKM matrix is non-diagonal, with both cs and cd matrix elements.

Particles from benchmark-decays go up to 1/2 to 1/3 of the momentum reached in binary decays of the p anti-p system, thus PID need not reach up to the full invariant mass (to discuss).
  Detector thickness in the active angular range: 10mm (or similar), fused silica with specific weight 2.2g/cm3, about 9% radiation length. The Li_F material in the solenoid shadow requires moderate precautions against radiation, a Japanese supplier website states.
Line: 11 to 20
  In the latest PANDA drawing (2006-4-24) there seems to be too little space foreseen to accomodate the focussing lightguide plus photon detectors part of this PID device.
