CALIBRATION OF THE MICRON OPTICS TEMPERATURE SENSORS FOR FIBER OPTIC THEMO-HYGROMETERS FOR CMS TRACKER

The nature of my project at European Organization for Nuclear Research (CERN) is proposed and discussed. The experiments at LHC (Large Hadron Collider) are conducted in high precision with state of the art in order to get a glimpse of the fundamental particle behaves in a re-created early universe environment by colliding particle with high energy. Trillion of data collected from the LHC has been studied by top scientists from all around the world to produce readable information and analyze the result. Optimization, data sorting, reconstruction, calibration, and fine tuning are constantly carry out at CERN in order to maintain the quality of each measurement. Therefore, tracker is primarily important and it is needed to be serviced frequently to maintain its efficiency in detecting the particle. Being a summer intern student at CERN, I was assigned to the project concerning Fiber Optic Thermo-Hygrometers which is currently deploying in CMS (Compact Muon Soleniod) detector in the upgrading period. The internship has been done in PH-DT Laboratory at CERN with the supervision of Salvatore Buontempo and co-supervision of Paolo Petagna and Gaia Berruti.
