Research Activities/ Ongoing Projects
- Development of the GEM control and monitoring system in CMS: The project focus on the design and the development on the GEM Detector Control System (DCS) including an FSM (Finite State Machine) using WinCC and its integration in CMS.
- Characterization and Performance studies of production chambers for the first GEM upgrade at LHC : During chamber construction, GEM undergoes quality controls. The main characterizations come from QC5, which determines the local GEM Gain (Amplification of the ionization of the mips in the drift region) and QC8, which determines mainly the local GEM efficiency for cosmic muons. Local means that the physical observables are measured in different positions of the chamber obtaining a map.
- Performance Studies of the GEM Detector Muon Upgrade at the CMS Experiment at LHC : The main requirements on the GEM detector are the efficiency and the space point resolution. In order to measure these quantities, it is necessary to acquire experience with the Muon reconstruction and follow and participate to the progress done with the Muon POG (Physics Object Group, under the Physics coordination).
- Impact of the environmental background to GEM detectors performance in CMS : Proton-proton collisions produce neutrons and photons that are main source of environmental background for CMS. GEM will be installed in regions where the fluxes are very high. The spurious hits produced can spoil the performance of the system. The Goal of this project is to understand the impact of the environmental background to GEM performance.
