Atmospheric Electron Spectrum above 30 GeV at the high altitude
Y. Komori, T. Kobayashi, K. Yoshida +1
We have observed the primary electron spectrum from 30 GeV to 3 TeV using emulsion chambers flown by balloons at the top of the atmosphere, for the purpose of exploring the origin…
Observations of High Energy Cosmic-Ray Electrons from 30 GeV to 3 TeV with Emulsion Chambers
Tadashi Kobayashi, Yoshiko Komori, Kenji Yoshida +7
We have performed a series of cosmic-ray electron observations using the balloon-borne emulsion chambers since 1968. While we previously reported the results from subsets of the ex…
High-energy electron observations by PPB-BETS flight in Antarctica
S. Torii, T. Yamagami, T. Tamura +23
We have observed cosmic-ray electrons from 10 GeV to 800 GeV by a long duration balloon flight using Polar Patrol Balloon (PPB) in Antarctica. The observation was carried out for 1…
Cosmic-ray spectra of primary protons and high altitude muons deconvolved from observed atmospheric gamma rays
K. Yoshida, R. Ohmori, T. Kobayashi +3
We have observed atmospheric gamma rays from 30GeV to 8TeV, using emulsion chambers at balloon altitudes, accumulating the largest total exposure in this energy range to date, SOT…
The Most Likely Sources of High Energy Cosmic-Ray Electrons in Supernova Remnants
T. Kobayashi, Y. Komori, K. Yoshida +1
Evidences of non-thermal X-ray emission and TeV gamma-rays from the supernova remnants (SNRs) has strengthened the hypothesis that primary Galactic cosmic-ray electrons are acceler…
Atmospheric gamma-ray observation with the BETS detectorfor calibrating atmospheric neutrino flux calculations
K. Kasahara, E. Mochizuki, S. Torii +13
We observed atmospheric gamma-rays around 10 GeV at balloon altitudes (15~25 km) and at a mountain (2770 m a.s.l). The observed results were compared with Monte Carlo calculations…
