Who I am: I am a master student in Nuclear and Subnuclear physics at the University of Bologna, Italy. I really enjoy coding and to play videogames. I am also a pianist and an astrophile!
Research: The new Muon g-2 experiment at Fermilab will measure the anomalous magnetic moment a of the positive muon with a precision of 140 parts per billion. This measurement is motivated by the result of the Brookhaven Laboratory experiment that in 2001 showed a 3.5 standard deviation discrepancy with the standard model prediction with a precision of 540 ppb. This experiment has several improvements, one of these is a laser calibration system for all the 1296 channels of the 24 calorimeters. My objective during this summer internship was to implement a calibration mode called double pulse that allows a study on the calorimeter response when two positrons hits the detector at the same time. The majority of the work was on the hardware, since I helped mounting and aligning the optics, soldered and prepared several cables used to control motorized mirrors, connected a Delay Generator to the NIM electronics and to the lasers. I also worked both on the software necessary to analyze the data and to communicate remotely with the devices located in the Laser Hut. Now the setup is ready and fully functioning, and some runs have been executed. At the end of my program, I also prepared and hosted an exhibit representing the Laser Calibration System to be shown to the 5000 people that came to Muon g-2 during the big Fermilab Open House event for the 50th anniversary.
