Description
The Hyper-Kamiokande (Hyper-K) experiment is a next generation underground water Cherenkov detector designed to search for leptonic CP-violation and a wide science program, including neutrino astrophysics, and searches for nucleon decay.
The experiment will use around 20000 PMTs of 20" to observe the inside of the HK tank. The collaboration chose a system based on discrete components and proposed by INFN as the electronics for the experiment.
The board has 12 channels and 2 different boards will go in a vessel so that a single vessel can be connected to 24 total PMTs.
A single channel is connected to two main blocks: the charge measurement circuit and the timing measurement circuit. The board is equipped with a Xilinx Kintex 7 FPGA which has the task of generating the integrator hold, the conversion signals for the ADCs and to measure the time with a TDC. The FPGA will also be responsible for the data collection from all the channels and the communication with the Digital-Processing-Board (DPB) that will connect the vessel with the DAQ of the experiment.
