Global-local-grouping multi-grid-type MSGC for neutron applications

We have designed, fabricated and tested a multi-grid-type microstrip gas chamber (M-MSGC) using the global-local-grouping (GLG) method with an active area of 6.4 cm x 6.4 cm. The plate was tested in the 1 atm Ar/CH4 gas and the plate was stably operated at the gas gain of ~1000. The local and the global position detection have been implemented in our ASIC front-end system.
