N2 - The CALET Gamma-ray Burst Monitor (CGBM) is the secondary scientific instrument of the CALET mission to be attached to the ISS, sensitive to X and gamma-rays from 7 keV to 20 MeV. The scientific goal of the CGBM is to search out a clue to radiation mechanisms of gamma-ray bursts (GRBs) by obtaining very broadband spectra from optical to TeV gamma-rays together with the primary instrument, the calorimeter (CAL) sensitive to GeV-TeV gamma-rays, and the star camera (ASC). The CGBM sensor consists of the hard X-ray monitor (HXM) sensitive to the 7-1000 keV range and the soft gamma-ray monitor (SGM) to 100 keV-20 MeV utilizing two LaBr3 (Ce) and one BGO scintillators. The LaBr3 crystals would be employed first for GRB observations in space. The electonics box (E-box) processing signals from the sensors, is equipped with analog circuits for a wide dynamic range, onboard GRB trigger system, and 10 Mbyte memory for GRB data accumulation. In this paper, we will describe the scientific performance and the development status of the CGBM.
