| Summary: | We present preliminary results on the spectrum of high energycosmic-ray electrons as the measured in the flightof the Polar Patrol Balloon (PPB) which lasted for 13 days,in January,2004 with a launch from Syowa Station, Antarctica.The PPB-BETS (Balloon-borne Electron Telescope with ScintillatingFiber) detector is designed to measure the cosmic-ray electron spectrumfrom 10 GeV to 1 TeV during a long balloon flight.It consists of 9 plates of plastic scinlater as a calorimeterand a scintillating fiber trackers for cascade showersinduced from high energy electrons and protonsbetween plates of lead with total 9 radiation length thickness.In this paper, we discuss the perfomance of the detectorand the preliminary results on the spectrum of cosmic-ray electrons. 35th COSPAR SCIENTIFIC ASSEMBLY |
