Radiation Hardness Study with Small Gap Chambers of 5 and 9 cm Strips.

Small Gap Chambers of 5 and 9 cm strips were exposed to a 5 kHz/mm2 pion beam of 300 MeV in the piM1 area at the PSI. We present the discharge rates and the strip failures measured at different voltages. The results are compared to the LHCC requirements. We extrapolate the expected safety margin and...

Sumario:Small Gap Chambers of 5 and 9 cm strips were exposed to a 5 kHz/mm2 pion beam of 300 MeV in the piM1 area at the PSI. We present the discharge rates and the strip failures measured at different voltages. The results are compared to the LHCC requirements. We extrapolate the expected safety margin and show the improvement that was obtained with two chambers equipped with GEMs. Summary: 1. Introduction 2. PSI data 3. Chamber signal to noise ratio 4. Radiation hardness 5. Conclusions
