Micro-Gap Chambers with self-aligned geometry

We report on the performance of Micro-Gap Chambers is 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 voltag...

Description
Summary:We report on the performance of Micro-Gap Chambers is 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.
