A photon detector for relativistic heavy ion collisions

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

The detection of direct photons produced in relativistic heavy ion collisions is discussed. Physics motivations and experimental difficulties are presented. After a description of the PHOS electromagnetic calorimeter of ALICE, I will present, how its identification capabilities can be substantially improved by adding a pre-shower detector (PPSD). The PPSD consists of a passive converter sandwiched between two large active area MICROMEGAS chambers. Preliminary results of the beam tests for the PPSD prototype will be also described.
