Abstract
We have operated successfully glass resistive plate counters in the streame r mode at the BELLE experiment by using a nonflammable gas mixture of argon 30 %, butane-silver 8 %, and freon, HFC-134a 62 %. This freon is non-ozone -depleting but has a high global warming potential (1300 times higher than that of CO2). Thus freon gases might be unusable in the near future. We tes ted the performance of a glass resistive plate counter operated in the stre amer mode with an alternative gas mixtures of argon, butane, CO2, and/or O- 2 gases and found an efficiency of about 90 %.
