Abstract:
High energy physics needs a complete set of instruments to study the response of gas detector when interacting with high energy particles. This kind of analysis requires not only the availability of a complete physics library but also the tools for using the intrinsic amplification mechanism of these detectors and the formation of the induction signal. The amplification of signal can be a computing intensive operation and can not be easily performed with the software currently available to the high energy physics community. In addition, the complex geometries used by modern gas detector require a specialized framework with support for complex geometry primitives. We create an application which simulates the Micromegas (Micro-MEsh Gaseous Structure) detector using the Geant4 framework. It is implemented using a semi-analytical approach to model the amplification of electrons and the signal induction on the detector strips. Integration with Magboltz is used to have a precise characterization of the gas medium. The current implementation is limited to the Micromegas gas detector but the concept used here can be generalized to other gas detectors.
