Accelerating avalanche simulation in gas based charged particle detectors

Abstract

The development and optimization of Micro Pattern Gaseous Detectors relies heavily on the simulation of the geometry, the avalanche process and the signal generation inside the detector. In complex scenarios where high detector gas gains are required, the simulation can be computationally expensive and can become a bottleneck for the R&D process. In this paper we present two approaches to reduce the simulation execution time when using the Garfield++ simulation package. We present the two approaches and discuss the results.
