Description
The T2K[1] collaboration is upgrading the near detector (ND280) with four additional subdetectors: a time of flight detector (TOF), two high-angle TPCs (HATPC), and the super fine grained detector (Super-FGD).
The Super-FGD consists of 2 million scintillator cubes read by optic fibers along three directions, allowing three-dimensional track reconstruction in a 2-tons fiducial mass detector. The remarkable advantages are low proton detection momentum threshold, neutron detection ability, and 4π angular acceptance. A crucial element for the success of this detector is the Front-End electronics, comprising more than 200 Front-End Boards (FEB) handling almost 60 thousand SiPM channels, designed by the University of Geneva and LLR (Paris).
This work presents the first performance studies of the read-out electronics, as well as a Functional Test fully designed at UniGe to reliably check the hardware quality of each of the 243 FEBs used in the detector. This is currently used as an electronics diagnostics tool on-site.
Furthermore, a detailed simulation of the read-out system is under development, offering an important instrument for the estimation of systematics uncertainties related to the PID capabilities of the detector.
The Super-FGD and its electronics have been successfully installed and integrated in ND280, currently taking neutrino-beam data.
