Novel glass ceramic-type micropattern gas detector with PEG3C

A new glass plate (GP) has been developed for a hole-type micropattern gas detector (MPGD). The material of the GP is a crystallized photosensitive etching glass (PEG3C) made by Hoya Corporation. A basic performance test of the hole-type MPGD was carried out using an X-ray beam with Ne-based gas mixtures at 1 atm. Gains of up to 5×103 and 6×104 were obtained using a single and a double GP, respectively. An energy resolution of 17% was obtained for 6 keV X-rays with a single GP. It was also shown that there is little charging-up effect in the GP. In this paper, we report the characteristics of the new hole-type MPGD with a GP made of PEG3C.
