Triggering and data acquisition for the Hyper-Kamiokande experiment

Abstract

Hyper-Kamiokande has been proposed as a next generation neutrino oscillation experiment capable of observing accelerator, atmospheric, solar and astrophysical neutrinos, as well as possible proton decays, providing a rich scientific program. One of the main goals is the study of CP violation in the lepton sector. The Hyper-Kamiokande detector will be an underground water Cherenkov detector with a fiducial mass of 0.56 million metric tons, approximately 25 times larger than that of Super-Kamiokande. With such a large fiducial mass, the Hyper-Kamiokande detector will need a robust trigger and data acquisition system (DAQ) to be sensitive to the physics events of interest. Several UK institutions are participating in the development of the trigger and DAQ. Here we present some of the on going studies from the UK DAQ group.
