抜粋

We had a long duration balloon flight for observing cosmic-ray electrons from 10 GeV to 1000 GeV by the Polar Patrol Balloon (PPB) in Antarctica. The observation was carried out for 13 days at an average altitude of 35 km in January 2004. The detector is an imaging calorimeter composed of scintillating-fiber belts and plastic scintillators inserted between lead plates. The performance of the detector has been confirmed by the beam test at CERN-SPS and also investigated by Monte-Carlo simulations. We have collected 5.7×103 events above 100GeV including nearly 100 candidates of primary electrons. Preliminary result of the electron energy spectrum in 100̃1000 GeV has been obtained.
