Beam tests of CALET with BBM electronics and STM at CERN-SPS
Abstract
We have been developing flight hardware of CALET (CALorimetric Electron Telescope) to observe electrons, gamma rays, and nuclei at the Japanese Experiment Module “Kibo” Exposed Facility (JEM-EF) on the International Space Station (ISS). The main calorimeter of CALET consists of a charge detector (CHD) to identify particles by charge, an imaging calorimeter (IMC) to determine incident angles and shower starting points, and a total absorption calorimeter (TASC) to measure energies and to discriminate electromagnetic particles from nuclei. We carried out beam experiments at CERN-SPS to confirm consistency between our simulation and beam test data. It is important for performance check and flight data analyses. We assembled a Beam Test Model detector by using BBM (Bread Board Model) of front end electronics and STM (Structure and Thermal Model) of CHD, IMC, and TASC for electron/proton runs in 2012. We made ion runs mainly to test CHD readout with BBM front end electronics in 2013. Basic results of the beam tests will be reported here.
