| Research Abstract |
A signal read-out system for a calorimeter for high energy cosmicray observation was studied. The research study involved the following three studies. 1) The performance of a dual photo-diode, which has an AP and a PN junction photo-diodein one ceramic substrate, was evaluated as a photo-sensor for the calorimeter. 2) The performance of a wide range read-out circuit using a hybrid IC was evaluated for the CALET experiment. 3) A front-end application specified integrated circuit(ASIC) was developed with a wide dynamic range amplifier to read out signals from a photo-sensor like a photodiode.
