Modern Muon Detectors

One of the most modern and advanced technology in gas detectors is GEM. Its flexibility and durability permit applications spanning from high energy physics experiments to medical instrumentation. The innovative detection principle, which relies on multiple stages of electron amplification, is still under study and new aspects are being discovered.

 
 

Cosmic Test Stand

The Cosmic Test Stand is a challenging project that aims to integrate multiple types of detectors in a versatile stand. The different nature of the deployed detectors allows to reconstruct cosmic muon tracks with high spatial resolution, good timing information and covering a large area. These characteristics allow to precisely explore the properties of modern muon detectors.

The key detector present in the Cosmic Test Stand are the Drift-Tube chambers. After the complex upgrade of the cosmic test stand's infrastructure, the performance of the DT chamber must be verified. The goal of the thesis is to test the performance of the DT chamber. As a part of the performance check the characterization of single gas tubes should be provided. The characterization procedure should be developed and provided under different conditions: HV levels and gas mixture.

Performance studies of GEM detectors

Guided by the results obtained in the simulations of GEM detectors, a wide number of parameters are being tested on prototype chambers. The goal of the thesis is the study of the performance of a GEM chamber, such as efficiency, gas gain and noise, in different conditions and varying the applied parameters.

Characterization of scintillator tiles and SiPM for the Cosmic Test Stand

The Cosmic Test Stand is a project that aims to integrate multiple types of muon detectors in a versatile setup. The different nature of the deployed detectors, give the possibility to reconstruct cosmic muon tracks with high spatial resolution, good timing information and covering a large area. These characteristics make it a suitable reference for precisely testing new generation muon detectors.

Different designs of 40 cm x 40 cm x 1 cm scintillator tiles, each read out by 4 SiPMs should be tested and characterized for their use as trigger detectors in order to optimize the working parameters that are going be used during the long term operation.

Microscopic simulation of modern gaseous detectors

To have a better understanding of the results coming from the experiments, the simulations of such processes are essential. The goal of the thesis is to simulate signal propagation in GEM chambers on a microscopic scale using the GARFIELD environment.
