Abstract :
The dead length, 6, for t > 20 ¿s is well approximated by ¿=¿0 exp(-t/¿) for mixtures of argon-isobutane with benzene or TEA. ¿0 varies in an approximate linear way with the streamer charge and the systematics of ¿ regarding the high voltage is also presented. Afterpulses are associated not only with wall effects but also with photoionization in the gas mixture itself. Interpretation of the data is attempted.
