Özet

A Monte Carlo simulation code has been developed in order to analyse the intrinsic performance of non-uniform electric field argon-based gas detectors and some calculated results are compared to precise experimental results. In the simulation electron transport, avalanche gain process and its fluctuation have been investigated for different bias voltages and gas mixture ratios in a well-defined device geometry. The results show that the relative variance of the avalanche gain distribution started by a single electron is more sensitive to small changes in low bias voltages. (C) 2004 Elsevier B.V.
