Freonless Gas Mixtures For Glass Rpc Operated In Streamer Mode

A glass Resistive Plate Counters (RPC) at the BELLE experiment, has been operated by successfully using a non flammable gas mixture of 30% argon, 8% butane-silver and 62% freon, HFC-134a. This freon is non-ozone 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. The performance of glass RPC operated in streamer mode with a nonfreon gas mixture of argon, butane, CO2 and/or O2 gases, and with an efficiency of around 90% has been tested.
