Sviluppo e test di un rivelatore a Micromegas per una possibile applicazione nello spettrometro di COMPASS++/AMBER

The thesis decribes the development of Micromegas detector prototypes for a possible application in future COMPASS++/AMBER experiment. Generalities of radiation detection are described, with a particular focus on micro-pattern gaseous detectors (MPGD) and Micro-Mesh Gaseous Structure Detectors (Micromegas). A Monte Carlo simulation of the first prototype has been performed using a toolkit of softwares (gmsh, elmer, Garfield++); software functioning and simulation results are presented. In the last section, assembling of the prototypes and results of the test are oulined.
