Abstract

We report on the performance of Micro-Gap Chambers manufactured at Strasbourg. We present measurements of gain as a function of various operating parameters, such as high voltages and various gas mixtures. With the optimal mixture of Ne-DME (70-30%), a cathode voltage of -500 V and a drift voltage of -2900 V, a gain of ∼ 3000 is achieved. Performance of Micro-Gap Chambers is compared to that of Micro-Strip Gas Chambers.
