We present measurements of the energy loss of pions and electrons in drift chambers (DC) operated with a Xe2CO2 (15%) mixture. The measurements are carried out for particle momenta from 1 to 6 GeV/c using prototype DC for the ALICE transition radiation detectors. Microscopic calculations are performed using input parameters calculated with GEANT3. These calculations reproduce well the measured average and most probable values for pions, but a higher Fermi plateau is required in order to reproduce our electron data. The widths of the measured distributions are smaller for data compared to the calculations. The electron/pion identification performance using the energy loss is also presented.
Energetické ztráty elektronů a p mezonů byly studovány v prototypových driftových komorách určených pro detektor přechodového záření TRD experimentu ALICE plněných směsí Xe, CO2(15%). Výsledky jsou srovnány s mikroskopickou simulací provedenou v programu GEANT3.
