Abstract

We present the analysis methodology and preliminary results of the gamma-ray event analysis using the CALorimetric Electron Telescope (CALET). CALET, a 30 radiation length deep calorimeter, was deployed aboard the International Space Station (ISS) in August 2015. In this work we demonstrate the sensitivity of CALET to gamma-rays, the efficiency of separation between gamma-ray and charged particle events, and CALET’s exposure on the sky after the first 17 months of observation. Consistency of the flux of the bright sources Geminga and the Crab with established Fermi-LAT results is discussed and initial results of a search for high-energy counterparts to CALET Gamma-ray Burst Monitor gamma-ray bursts are presented.
