Description
In order to be ready for the era where statistical uncertainty will not be dominant anymore, the T2K collaboration has started the second phase of T2K requiring the Near Detector (ND280) Upgrade with a significant reduction of systematic uncertainties with respect to what is currently available. One of the key sub-detectors of upgraded ND280 is the Super Fine Grained Detector (Super-FGD) which has an innovative configuration of fine-grained fully active plastic scintillator cubes. The cubes’ size is 1 × 1 × 1 cm and the active part of Super-FGD is 182 × 192 × 56 cubes in dimension. These cubes are optically independent and read out along three orthogonal directions by wavelength shifting (WLS) fibers connected with Multi-Pixel Photon Counter (MPPC) totalling more than 56k channels. The new configuration of Super-FGD provides 3D reconstruction, full polar angle acceptance and a much lower proton tracking threshold. Furthermore, neutron tagging capabilities in addition to precision timing information will allow the upgraded detector to estimate neutron kinematics from neutrino interactions. All the features above have put many requirements for read-out electronic systems such as a large number of channels, a large dynamic range (from ~0.5 p.e up to 1500p.e), and a time resolution of sub-ns. These tasks are achievable thanks to the Front-End Board (FEB) where its electronics architecture revolves around the utilization of the Cherenkov Imaging Telescope Integrated Read Out Chip (CITIROC). Each FEB can read 256 channels and there is more than 200 FEB in total. In this poster, we will briefly present the Super-FGD and its expected performance then focus on characterizing the architecture of the FEB, together with a summary of its performance test series before mass production.
