概要 国際スペースステーションで宇宙線観測を行うことを目的とした2500kgの観測装置CALETを提案しており、シミュレーションや加速器実験による装置性能評価と開発状況、およびスペースステーションへの搭載性についての検討を報告した。
We propose the CALorimetric Electron Telescope (CALET) mission for Japanese Experiment Module, Exposed Facilisty (JEM-EF) on ISS to address some of the most profound questions in particle astrophysics. CALET is composed of two kinds of calorimeter, an imaging calorimeter, IMC, at upper part and a total absorption calorimeter, TASC, at lower part. The IMC is employed to detect the shower profile by using scintillating fibers with 64-anode PMT read-out system. The TASC is consisted of BGO logs to measure the energy deposits in each shower. Total weight of the payload is nearly 2,500 kg and the geometrical factor for electrons is about 1 m2 sr. CALET has a unique capability to measure electrons and gamma-rays beyond 1 TeV since it can have a superior hadron rejection power of 106 for electrons and much better for gamma-rays. It can also measure protons and heavy nuclei in proximity of the Knee. The energy resolution for electromagnetic particles is better than a few % above 100 GeV. We will present a baseline design of the detector, and report the present status of detector development. Compatibility of the detector with the JEM Exposed Facility will also be discussed.
