We have developed an ASIC for readout of a 144 channel HAPD (hybrid avalanche photo-detector), one of the candidate photo-detectors for use in the aerogel RICH detector of the Belle upgrade (Belle-II). The first series of ASICs for evaluation showed good performance, and have been used to successful

A new hybrid avalanche photo-detector has been developed as a photon sensor for the Belle II RICH counter. Single-photon response was investigated in the presence of a magnetic field and excellent performance was demonstrated. In addition, the radiation damage due to the neutron dose was studied. By
