Abstract

We are developing a total absorption calorimeter (TASC) of the CALET (CALorimetric Electron Telescope) instrument for observing high energy electrons and gamma rays on the ISS (International Space Station). A read-out system using a multi-photodiode and a front-end circuit including analog ASIC, 16 bit ADC and FPGA has been developed to measure the energy deposit with the dynamic range from 1MIPs(Minimum Ionization Particle) up to 106MIPs in a BGO bar of TASC. The output signal of 1 MIP was calibrated by cosmic-ray muon. The ADC count of light yield of BGO by a cosmic-ray muon was 10.8fC on average. The dynamic range of the read-out system was confirmed from 1MIPs to about 2400 MIPs with both of LED pulse and heavy ions beam.
