We are developing the CALET (CALorimetric Electron Telescope) instrument for observing high energy electrons
and gamma rays on ISS. For conrming the CALET capability expected by simulations, we made a
scale model of CALET with a size of 2/3 in thickness and had the experimental tests by using beams available
in CERN. The beams used are 50GeV, 100GeV electron and 150 GeV proton. The energy resolution is
σ/E=4.0±0.1% and 2.25±0.04% for 50GeV and 100GeV electrons, respectively. About 97.3% of protons
can be rejected by shower image with Total Absorption Calorimeter, TASC, while approximately 96.8% of
electrons were correctly identied. The performance of the scale model was also investigated by Monte Carlo
simulation to compare with the results by beam tests. We conrmed good consistency between simulation and
the beam test.
