  • Abstract
    Here we report the performance of Glass GEM. Our new GEM is fabricated in totally new process with photo-etch able 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 700μm thick GEM with Cr and Cu layer electrodes. Glass GEMs enable to overcome the drawbacks of conventional polyimide GEMs, such as non-uniformity, smaller gain, and the outgas from the material. With the Glass GEM, we obtained 3×104 gas gain with a 5.9 keV (Fe-55) X-ray source.
