Performance of the EM end-cap presampler in the 1999 testbeam run

Two electromagnetic end-cap presampler modules were tested together with the EM end-cap calorimeter Module 0 on H6 SPS electron beam at CERN in September-October 1999. The results on energy resolution for electrons with energy in the range 20-100 GeV and various amounts of upstream dead material are...

Sumario:Two electromagnetic end-cap presampler modules were tested together with the EM end-cap calorimeter Module 0 on H6 SPS electron beam at CERN in September-October 1999. The results on energy resolution for electrons with energy in the range 20-100 GeV and various amounts of upstream dead material are presented. They are found in agreement with simulation. It is shown that using of the presampler allows one to account for the energy loss in upstream material and thus considerably recover the degradation of the energy resolution. The results of noise and crosstalk calculation and measurement in calibration as well as in data runs are also reported.
