Assembly and measurements of the Electromagnetic Calorimeter components   for "WASA at COSY" setup
  This work describes the tests of the scintillator electromagnetic calorimeter of theWASA detector setup after transferring it from the CELSIUS storage ring at The Svedberg Laboratory(Uppsala, Sweden) to the Cooler Synchrotron COSY at the Institut fur Kernphysik (IKP) of Forschungszentrum Julich, Germany. The tests were performed using gammas of 4.4MeV energy from an AmBe source. The status of the CsI(Na) crystals was determined and the indication of gain factor for the energy calibration was extracted.
