Beamtest of non-irradiated and irradiated ATLAS SCT microstrip modules at KEK

Non-irradiated and irradiated ATLAS SCT barrel and forward modules were beamtested with 4 GeV/c pions. Pulse shapes confirmed the peaking time of the amplifier to be 22 ns and deteriorated slightly in the irradiated modules. Median charges saturated around 3.8 fC both in the non-irradiated and irrad...

Zusammenfassung:Non-irradiated and irradiated ATLAS SCT barrel and forward modules were beamtested with 4 GeV/c pions. Pulse shapes confirmed the peaking time of the amplifier to be 22 ns and deteriorated slightly in the irradiated modules. Median charges saturated around 3.8 fC both in the non-irradiated and irradiated modules. Signal/Noise ratios, using the noises 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.
