Abstract
We have operated successfully glass Resistive Plate Counters (RPC) at the BELLE experiment by using a nonflammable gas mixture of 30% argon, 8% butane-silver and 62% freon, HFC-134a. This freon is nonozone depleting freon, but a freon has a high global warming potential in general. Thus a gas mixture for RPC might be desired to be freonless in the near future. We have tested the performance of glass RPC operated in streamer mode with a nonfreon gas mixture of argon, butane, CO2 and/or O2 gases, and found an efficiency of about 90%.
