Positive synergism in binary gas mixtures is studied by means of fast time-resolved current measurements willl a time resolution of 1.4 ns. In this paper we present experiments in pure I-C3F6, in pure c-C4Fg and in an optimized mixture of 40% I-C:JF6 and 60% c-C4Fg. We have experimentally verified that the mixture of I-C3F6 and c-C4Fs has a higher rate of conversion from unstable negative ions to stable ones than either of the two constituent gases. This enhanced stabilization rate is responsible for the observed synergetic effect. The conclusions are supported by an extended avalanche model which includes electron detachment and stabilizing ion conversion processes, next to the commonly assumed ionization and attachment processes.
