    The CALET mission is a Japanese-led effort involving candidate experiments on the International Space Station, planned for launch in 2013. The CALET main detector is a pair conversion telescope which is dedicated to observing high energy electrons and gamma-rays in the GeV-TeV range. CALET can observe gamma-ray bursts over an unprecedented 9 decade energy range from ∼keV to ∼TeV with a combination of a gamma-ray burst monitor (GBM) with low energy coverage. GBM is now designed as multiple scintillators made of BGO and LaBr3 (Ce) scintillators. The prototype LaBr3(Ce) crystal with 3 inch diameter and 0.5 inch thickness displays a very good performance: 2.9±0.1 % FWHM energy resolution at 662 keV and 4 keV lower energy threshold. Furthermore, degradations in performance by the anticipated proton irradiation in the orbit are not significant. Results on proton-induced background are also presented.
