Abstract：
The research results of a thin multiwire chamber operating with strongly quenching gas and its discharge mechanism are presented in this paper. It is indicated by experiments that high gas gain and fast time response could be achieved simultaneously because of operating in the saturated mode. The effect of space charges and the emergence and action of ionizing photons are essential factors in its discharge mechanism, but the latter factor is restrained by the strongly quenching gas.
