Abstract

We have observed cosmic-ray electrons from 10 GeV to 1 TeV with PPB-BETS by a long duration balloon flight using Polar Patrol Balloon (PPB) in Antarctica. The observation was carried out for 13 days at an 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 geometrical factor of detector is about 600 cm2sr and the total thickness of lead absorber is 9 radiation lengths. We have collected 5.7103 events over 100 GeV including nearly 100 candidates of primary electrons. During the flight, sun aspect sensors and geomagnetic aspect sensors operated to determine the attitude of the instrument. The arrival directions of high-energy electrons over 100 GeV, together with the energy spectrum, are suggested to be a powerful probe to identify nearby cosmic- ray electron sources. In this paper, we present the energy spectrum and arrival directions of cosmic-ray electrons from 100 GeV to 1 TeV observed with PPB-BETS.
