Abstract
We demonstrate nearly approximation-free electrostatic calculations of micromesh detectors that can be extended to any other type of micropattern detectors. Using a newly developed Boundary Element Method called Robin Hood Method, we can easily handle objects with huge number of boundary elements (hundreds of thousands) without any compromise in numerical accuracy. In this paper we show how such calculations can be applied to Micromegas detectors by comparing electron transparencies and gains for four different types of meshes. We also demonstrate the inclusion of dielectric material by calculating the electric field around different types of dielectric spacers.
