Experiment Description

Research Overview

  • CALET aims to investigate high energy cosmic rays, extending the observations carried out by previous balloon experiments and space missions so far. The instrument measures high energy particles with superior energy resolution and excellent particle identification capability. 

  • CALET addresses many of the outstanding questions of high energy astrophysics, such as the origin of cosmic rays, the mechanism of cosmic-ray acceleration and galactic propagation, the existence of dark matter and nearby cosmic-ray sources.

  • CALET provides an important window on the high energy phenomena taking place in the galaxy by studying cosmic rays.  Discovering the first experimental evidence of the presence of nearby cosmic-ray sources is one of the main goals of CALET.

Applications

Space Applications
CALET addresses many outstanding high-energy astrophysics questions such as the origin of cosmic rays, how cosmic ray accelerate and travel across the galaxy; the existence of dark matter and nearby cosmic-ray sources.  An inventory of the highest-energy radiation encountered in space also helps in characterizing the radiation environment encountered by humans and space electronics, and the risks they face.

Earth Applications
CALET expects to provide an important window on the highest-energy phenomena in the galaxy by studying cosmic rays, and seeks the first experimental evidence of the presence of nearby cosmic-ray sources. CALET's long exposure in space may also yield evidence of rare interactions between matter and dark matter.
