Abstract

The RPC(resistive plate counter) has good time and position resolution. These factors make it an attractive candidate for trigger system at collider experiment. The standard gas mixtures (Ar+iso-C4H10+Freon) used in RPC are very flammable when leaked into air. In view of safety issue,we have studied non-flammable gas of Ar+CO2+iso-C4H10+Freon as a function of ratio Ar.CO2 allowed in non-flammable gas mixtures for the RPC with ABS electrodes.The basic performance of the various mixtures have been measured; singles(untriggerd) count rate, detection efficiency and charge spectra versus operating voltage. We have found a set of non-flammable mixtures of the kind of Ar+CO2+ Freoii contained less than ∼ 8.4% of isoC4H10 for KL/muon counter of KEK B-factory at KEK.
