概要 国際宇宙ステーションにおける宇宙線観測を目指すCALET観測装置のプロトタイプbCALET-1を開発製作し、三陸大気球観測所より放球して行った宇宙線電子、大気ガンマ線の観測結果についての報告。
We carried out a balloon observation of cosmic rays using a prototype of the CALET at the
Sanriku Balloon Center of the Japan Aerospace Exploration Agency. The prototype detector consists of
1024 scintillating fibers for track imaging and 24 BGO scintillator ”logs” for total absorption of showers.
The observation was carried at an altiude between 35 and 37 km for about 3.5 hours. We measured
electrons and
-rays in the energy region between 1 to 100 GeV, and 20 MeV to 1 GeV, respectively.
In addition to verification of the prototype system, we have obtained the electron flux which is useful
to investigate solar modulation. Now we are planning a series of balloon experiments with larger-scale
detectors and longer-duration flights, which includes one-month observation by a super-pressure balloon.
