微带气室（MSGC）遭受由于表面流光放电。为了克服这个问题，我们提出了一种新的图案化方法，它利用阳极和阴极之间的中间电极。这种新型多栅型MSGC（M-MSGC）实现了高增益和高计数率能力。此外，我们提出了另一种信号读出方法，以获得在背板上的感应信号。浮置焊盘靠近M-MSGC前表面上的阴极条放置，感应电荷通过焊盘读出。我们正在研制一台用于中子散射实验的带板读出的M-MSGC。/sup 3/He M-MSGC已研制成功，并进行了实验测量。
A microstrip gas chamber (MSGC) suffers from discharges due to surface streamers. To overcome this problem, we have proposed a new patterning approach which utilizes intermediate electrodes between the anode and the cathode. This new multi-grid type MSGC (M-MSGC) realizes high gain and high counting rate capability. Furthermore we proposed another signal readout method to obtain induced signals on the back plane. Floating pads are placed close to the cathode strip on the front surface of an M-MSGC and induced charges are read out via pads. We are now developing an M-MSGC with pad readout for a neutron scattering experiment. /sup 3/He M-MSGC was developed and test measurements have been performed.
