CALET是一种空间仪器，旨在对国际空间站JEM-EF外部平台上的高能宇宙射线进行精确测量，自2015年10月中旬以来一直在收集科学数据。CALET的主要目标是确定附近的高能电子源和电子谱中暗物质的可能特征，除此之外，CALET还对从质子到铁甚至更高（Z = 40）的元素的能谱、相对丰度和次级与初级比进行广泛的测量，研究银河系粒子传播和加速的细节。CALET的基础上采取的数据在头三年的观测的概述，包括直接测量的电子+正电子能谱从11 GeV到4.8 TeV。测量质子谱的范围从50 GeV到10 TeV，这是第一次用单一的空间仪器测量，涵盖了以前用磁分光计和量热仪器在单独的子范围内研究的整个能量区间。宇宙射线核的初步光谱，连同伽马射线观测和搜索的e.m.。LIGO/Virgo GW事件。
The CALorimetric Electron Telescope CALET is a space instrument designed to carry out precision measurements of high energy cosmic-rays on the JEM-EF external platform on the International Space Station, where it has been collecting science data continuously since mid October 2015. In addition to its primary goal of identifying nearby sources of high-energy electrons and possible signatures of dark matter in the electron spectrum, CALET is carrying out extensive measurements of the energy spectra, relative abundances and secondary-to-primary ratios of elements from proton to iron, and even above (up to Z = 40), studying the details of galactic particle propagation and acceleration. An overview of CALET based on the data taken during the first three years of observations is presented, including a direct measurement of the electron+positron energy spectrum from 11 GeV to 4.8 TeV. The proton spectrum has been measured from 50 GeV to 10 TeV covering, for the first time with a single space-borne instrument, the whole energy interval previously investigated in separate sub-ranges by magnetic spectrometers and calorimetric instruments. Preliminary spectra of cosmic-ray nuclei are also presented, together with gamma-ray observations and searches for an e.m. counterpart of LIGO/Virgo GW events.
