Abstract
A thinner-THGEM (Thick Gas Electron Multiplier) with a thickness of 200 μm and small rim has been produced by high speed drilling and global etching. Some performances have been studied and the working conditions have been tested and selected, using various Ar and Ne based gas mixtures. Gain values above 3×103 under relatively low working voltage, energy resolution of 15.9% with 5.9 keV X-rays and good gain stability are obtained. Using Monte Carlo simulation, the dependence of the energy resolution on drift electric field was analyzed and compared with experimental results.
