Investigation of the Effect of Temperature on the Maximum Amplitude of the ToF Detector SiPM Arrays and Proposed SAMPIC Population Scheme

The phenomenon of neutrino oscillations was the first clear evidence of physics beyond the Standard Model, and following this discovery neutrino physics continues to shed light on and improve our understanding of the universe. The T2K experiment in Japan is an experiment currently studying neutrino oscillations and it has been a leader in oscillation analyses for the 12 years since the start of its operation in 2010. [3] However, it is now being upgraded to handle greater neutrino fluxes and to increase its sensitivity. Part of this upgrade is the installation of a new fine-grained plastic scintillator known as the superFGD, two high-angle Time Projection Chambers (TPCs) and the Time of Flight detector (ToF).[3] In this report, we accomplish two tasks. First we propose a system to populate the DAQ system with the output channels of the ToF. Second, we analyse data taken from a single position on a ToF bar to investigate whether the amplitudes of signals recorded by the SiPM arrays mounted on the bar vary with temperature. The data from two runs separated by nearly two months was compared and a clear pattern was not observed.
