摘要

The CALET payload will be installed in the Japanese Experiment Module Exposed Facility (JEM-EF) ofthe International Space Station (ISS). We developed a balloon-borne payload to evaluate the performance of CALET bycarrying out precursor flights for the electron and gamma-ray observations. The first flight of bCALET-1 (balloon-borneCALET prototype) was carried out in 2006, and the enhanced version, bCALET-2, was successfully flown in August2009. The bCALET-2 is composed of IMaging Calorimeter (IMC) and Total AbSorption Calorimeter (TASC). The IMChas an area of 256 mm × 256 mm, and is consisted of 8 layers of scintillating fiber belts with a total 3.6 radiation lengthsof tungsten plates interleaved within the fiber planes for imaging the pre-shower development. TASC is consisted ofcrossed BGO logs (25 mm × 25 mm × 300 mm in each) with a total of 13.4 radiation lengths depth, for measuring thetotal energy deposit of incoming shower particles. The geometry factor is nearly 320 cm 2 sr over 10 GeV. We succeededthe observation of the electron energy spectrum in 1 GeV several 10 GeV electron and the atmospheric gamma-raysin 1 GeV a few 10 GeV, which are consistent with previous observations by BETS. The results are compared withsimulations for confirming the detector performance.
