69. Micro Pixel Chamber with resistive electrodes for spark reduction

Dr Atsuhiko Ochi (Kobe University (JP))

02/07/2013, 17:05

The Micro Pixel Chamber (μ-PIC) using resistive electrodes have been developed and tested. The surface cathodes are made from resistive material, by which the electrical field is reduced when large current is flowed. Two-dimensional readouts are realized by oth anodes and pickup electrodes, on which signals are induced. High gas gain (>50000) was measured using 55Fe (5.9 keV) source, and very...

A novel gas-avalanche patterned hole electron multiplier, based on the 2D-THCOBRA concept, is presented. The microdot-THCOBRA (µdot-THCOBRA) presented in this work has active area of 10 × 10 cm2 and was specially designed for imaging purposes. It is a double-sided structure made out of a 0.4 mm thick G10 plate, covered with 50 µm of copper on both sides. Similarly to the 2D-THCOBRA, on the...

71. Performance of Glass GEM

We report first concise review on Glass GEM. Our new GEM is fabricated in totally new process with photo-etchable glass. The glass is called PEG3, the photo-etchabale glass material manufactured by HOYA-PENTAX co. ltd. With this material, we succeed in fabricating a 400 to 840µm thick GEM with Cr and Cu layer electrodes. Glass GEM enables to overcome the drawbacks of conventional polyimide...
