The CALET (CALorimetric Electron Telescope) experiment on the International
Space Station (ISS) is designed to observe cosmic-ray electrons, γ-rays,
and heavy nuclei. The CALET detector will comprise an imaging calorimeter
(IMC) and a total absorption calorimeter (TASC). The IMC part will be assembled
with several ten thousand scintillating fibers (SciFi). In order to read the
SciFi’s, we have been developing a readout system for multi-anode PMT (MAPMT).
We assembled a test detector using 512 SciFi’s and a MA-PMT readout
unit composed of ”Viking” chips (VA32HDR2). We report the performance of
the readout unit as proved by beam tests.
