Micro-Pattern Gas Detectors: State of the Art and R&D

Gaseous detectors are radiation detection instruments designed to point out the presence of ionizing particles and to measure their properties. They use the ionizing effect produced by the incoming particle onto a gas-filled sensor. The classical wire chambers, that were one of the first gas detectors, have a lot of advantages, but have also a limited rate capabilities. Then, in the 1980s, were introduced the Micro Pattern Gas Detectors (MPGDs) that perform better than classic wire chambers. The aim of my work as Summer Student was simulate, optimize and produce two new kind of MPGD: conic Thick GEM (ThGEM) and Spiral Detector.
