概要 国際宇宙ステーションへの搭載を目指す宇宙線観測装置CALETについて、装置の性能評価、期待される観測成果、開発状況などを報告した。
We are developing the CALorimetric Electron Telescope, CALET, mission for the Japanese
Experiment Module Exposed Facility, JEM-EF, of the International Space Station. Major scientific
objectives are to search for the nearby cosmic ray sources and dark matter by carrying out a precise
measurement of the electrons in 1 GeV - 10 TeV and γrays in 20 MeV - several TeV. CALET
has a unique capability to observe electrons and γrays over 1 TeV since the hadron rejection power
can be better than 105 and the energy resolution better than a few % over 100 GeV. The detector consists
of an imaging calorimeter, SciFi and W, and a total absorption calorimeter, BGO. CALET has
also a capability to measure protons and nuclei up to 1000 TeV, and it will have a function to monitor
solar activity and γray bursts with additional instruments. The phase A study has started on a schedule
of launch in 2013 by H-II Transfer Vehicle (HTV) for 5 years observation. Details of each part of
CALET will be presented in accompanying papers in this conference.
