A Computer-Simulation Model for Self-Quenching Streamer (SQS) Propagation Induced by Ionization Track of Alpha-Ray
A computer simulation model has been designed to check the validity of newly-proposed mechanism of self-quenching streamer (SQS) induced by α-rays in gas counters. This com- putation model reproduces the SQS propagation through a series of successive avalanches which are initiated by free electrons created along an ionization track of incident α-ray. In spite of a simple modeling with some approximations, computed results show good agreement with the observed ones in nature. This means the computation model based on the newly- proposed mechanism successfully interprets the essence of the SQS phenomenon induced by α-rays.
