Abstract

Due to its high primary and secondary ionization, dimethylether (DME) is often used for microstrip gas counter operation. The addition of neon (Ne) reduces the cathode strip voltage to reach full efficiency. A long efficiency plateau is important to maintain a good performance of the detector after a long exposure to high radiation levels. However, the electron drift velocity measurements showed that the Ne/DME mixture is too low for operation at high rate experiments and the price of neon is higher than other commonly used gases. Hence, the possibility of replacing neon by helium or argon and to add CO2 was studied.
