| 内容記述 | We accomplished a balloon observation of the high-energy cosmic-ray electrons in 10-1000 GeV to reveal the origin and the acceleration mechanism. The observation was carried out for 15 days at an average altitude of 35 km by the Polar Patrol Balloon (PPB) around Antarctica in January ,2004. The detector is an imaging calorimeter composed of scintillating-fiber belts and plastic scintillation counters sandwiched between lead plates. The geometrical factor is about 600 cm^2sr, and the total thickness of lead absorber is 9 radiation lengths. The performance of the detector has been confirmed by a test flight at the Sanriku Balloon Center and by an accelerator beam test using the CERN-SPS (Super Proton Synchrotron at CERN). The new telemetry system using the Iridium satellite, the power system supplied by solar panels and the automatic flight level control operated successfully during the flight. We collected 5.7*10^3 events over 100 GeV, and selected the electron candidates by a preliminary data analysis of the shower images. We report here an outline of both detector and observation, and the first result of the electron energy spectrum over 100 GeV obtained by an electronic counter. |
