JAXA's gamma-ray observation experiment, called "CALET" (CALorimetric Electron Telescope), which has been prepared for the Kibo Second Phase Utilization, entered its development stage.

Reviews and evaluations of the CALET were held by the "International Space Station/Kibo Utilization Promotion Committee" and "JEM Exposed Facility Subcommittee".

Payload Name CALET: CALorimetric Electron Telescope
Project Proposer Waseda University
Principal Investigator Shoji Torii
Mission Overview

CALET will investigate dark matter and origin of high energy electron / proton / atomic nucleus from deep space, by observing high energy electron beams and arrival directions of the cosmic rays, including gamma ray and high energetic electron beams.

CALET will cover larger energy band. Therefore, higher energy particles (unprecedented level) can be measured comparing to other existing observation equipment aboard the ISS and other observation satellites.

CALET aims at accurate and precise observation of an electron / gamma ray (the range of tera-electron volt) and the proton / atomic nucleus in the range of peta-electron volt. This kind of observation is the first attempt in the world.

CALET will undergo design, production and test phases, and will be launched to the ISS aboard the H-II Transfer Vehicle (HTV), KOUNOTORI, in 2014. The CALET will be installed on Kibo's Exposed Facilty (EF) by the JEM Remote Manipulator System (JEMRMS).
