Abstract :
We recently developed a Glass GEM (G-GEM), and it exhibited a superior performance. We also developed a G-GEM with a single-sided guard ring structure, in order to improve its spark tolerance. The guard ring G-GEM also showed good performance. The gas gain reached 7,500 with a single G-GEM setup. Energy resolution was 17.3% at maximum, with the collimated 6 keV X-ray source. Nowadays, large-area micro pattern gaseous detectors are required not only in physics field, but also in medical application or neutron detection application. Therefore, we are currently developing a large-area G-GEM. In this research, we will show the results of the preliminary experiments with it. Gas gain reached up to around 1000. The energy resolution was 33.6% at gain ~1,000.
