We investigated the behavior of ATLAS RPC counters in a temperature range from about 20 °C to about 30 °C. The counter gas volumes are made of low resistivity (from 1÷4dot operator1010Ωdot operatorcm) phenolic-melaminic polymers with linseed oil inner surface treatment and polycarbonate spacer. The measurements show that the counter properties related to the gas amplification (such as efficiency and cluster size) scale simply with temperature, but the counter properties related to the inner surface quality (such as dark current and noise rate) increase sensibly faster.

Abstract
We investigated the behavior of ATLAS RPC counters in a temperature range from about 20 °C to about 30 °C. The counter gas volumes are made of low resistivity (from 1÷4dot operator1010Ωdot operatorcm) phenolic-melaminic polymers with linseed oil inner surface treatment and polycarbonate spacer. The measurements show that the counter properties related to the gas amplification (such as efficiency and cluster size) scale simply with temperature, but the counter properties related to the inner surface quality (such as dark current and noise rate) increase sensibly faster.File in questo prodotto:
