Abstract :
Several types of two-dimensional multi-grid-type micro strip gas chambers (M-MSGCs) are being developed for the new spallation neutron source in Japan. In this paper, we propose a new type of M-MSGC using multi-layer technology. In order to reduce the number of readout lines, we introduce a new encoding scheme, the Global-Local Grouping (GLG) method. In this approach, global and local signals are used to locate the coarse and fine position, respectively. We have designed, fabricated and tested the GLG M-MSGC plate with an active area of 10×10 cm2. The results confirmed that the new type of M-MSGC can be operated properly.
