Space charge in drift chambers operated with the Xe, CO2(15%) mixture
Original language description
Using prototype modules of the ALICE Transition Radiation Detector (TRD) we investigate space-charge effects and the dependence of the pion rejection performance on the incident angle of the ionizing particle. The average pulse height distributions in the drift chambers operated with the Xe, CO2(15%) mixture provide quantitative information on the gas gain reduction due to space charge accumulating during the drift of the primary ionization. Our results demonstrate that the pion rejection performance ofa TRD is better for tracks which are not at normal incidence to the anode wires. We present detailed simulations of detector signals, which reproduce the measurements and lend strong support to our interpretation of the measurements in terms of space-charge effects.

Prostorový náboj v driftových komorách pracující se směsí Xe, CO2(15%)
Czech description
V prototypových modulech detektoru ALICE TRD bylo studováno působení prostorového náboje na účinnost vyřazení p mezonů v závislosti na úhlu jejich dopadu. Výsledky ukazují na lepší schopnost odlišení elektronů a p mezonů pro dráhy, které nejsou kolmé k anodovým drátům. Interpretace výsledků je podpořena simulacemi.
