CALorimetric Electron Telescope (CALET)

This is Japan's fifth experiment facility attached to the exposed facility on "Kibo". This cosmic ray observation facility observes the direction and energy from high energy electron rays, gamma rays, and other cosmic rays. It is hoped that CALET will lead the world in revealing the following mysteries which remain unexplained since cosmic rays had been firstly found 100 years ago:
- Acceleration/propagation mechanism of high energy cosmic rays
- Dark matter
- Gamma-ray burst
We are developing CALET for JAXA as well as multi-mission consolidated equipment. In August 2015, CALET was transported to ISS on HTV5 and commenced operation.
