Beamtest of Non-irradiated and Irradiated ATLAS SCT Microstrip Modules at KEK

Abstract

-Non-irradiated and irradiated ATLAS SCT barrel and endcap modules have been beamtested with 4 GeV/c pions. Pulse shapes confirmed the peaking time of the amplifier to be 22 ns with slight deterioration in the irradiated modules. Median charges saturated around 3.8 fC both in the non-irradiated and irradiated modules. Signal/Noise ratios, using the noise estimates from the in-situ calibration, were >16 in the non-irradiated (>150 V), and >10 in the irradiated (>300 V) barrel modules. No excess common-mode noise was observed.
