Numerical simulation of gaseous ionization detectors

Here, various approaches adopted to numerically simulate the detailed device physics of gaseous ionization detectors. Related experimental efforts will also be mentioned. Mathematical formulations, algorithms and simulation frameworks will be touched upon, in general. In particular, focus on several physics issues that author have addressed in recent times, such as, a) effects of non-uniformities and imperfections on device response, b) estimation of gain, spatial, temporal and energy resolutions, c) effects of electronic heating on device performance, and d) estimation of ion backflow in Micromegas - (single and double mesh) and GEM - (single and layered) based detectors
