megas: development and validation of a new simulation tool for the Micromegas detectors
We present megas, a new software tool that improves the simulation of the Micromegas gas detectors. Our tool offers the possibility to configure multiple arrangements with one or more layers of MM detectors. A series of simple commands can easily modify the constructive properties of each of these detectors, such as dimensions, gas composition, and electric field. megas is based on Betaboltz, an open-source library that simulates the step by step movement of electrons in an electric field using Monte-Carlo methods. A real-life example was simulated, and to validate our application, we perform a detailed analysis of our data compared with the actual experimental results. We present a selection of data obtained simulating real user-case scenarios, compared with results available in the literature, especially in the upgrade phase of the Muon Spectrometer of the ATLAS detector at LHC.
