    • Question during the presentation
      • Angular resolution of the EMC backward endcup?

      • Witch wave length %$\lambda$% is max for the APD, is match with the crystals light emission?
      • why not put one preamp. per APD? 1 HV cable for two APD with the same HV ?
      • How you define the noise level?
      • why if you increase the HV the noise decrease?
