Abstract:

The article describes the final conclusions of the RD-28 collaborative effort to develop the Micro-Strip Gas Chambers (MSGCs). The MSGCs have attracted a lot of interest due to many promising features: good position accuracy and two-track resolution, high rate capability and low cost. The article describes solutions to many difficulties, such as stability problems observed at high radiation rates attributed to substrate charging up and modifications, and ageing due to gas polymerization.
