Description
Multi-channel MPPC readout ASICs used in the near detector of the T2K experiment are all made outside Japan.
Some of the ASICs will be obsolete when Hyper-Kamiokande goes into operation in 2027 and cannot be reproduced.
Therefore, we will need to replace them with other types of ASIC.
Though it is possible to use other conventional ASICs made outside Japan, ASICs made in Japan have an advantage in terms of availability, because there are many experiments that use MPPC in Japan.
Against the above background, a new ASIC was developed in KEK and a prototype board was made using it.
In my poster, I will present the result of the evaluation of resolution, linearity, and channel-to-channel crosstalk of the prototype.
