Development of high rate MSGCS: overview of results from RD28

Many laboratories world-wide have contributed to the R&D project RD-28 at CERN (development of high rate micro-strip gas chambers). Various aspects of the design and use of the detector have been studied, in particular those connected with long-term operation in a high radiation flux. This paper summarizes some major outcomes of the research: the development of controlled resistivity substrates, the studies of pollution-induced ageing processes, the effects of substrate and metallization on performance, the operating characteristics in beam conditions.
