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…

Underground Water Cherenkov Muon Detector Array with the Tibet Air Shower Array for Gamma-Ray Astronomy in the 100 TeV Region
The Tibet AS Gamma Collaboration, M. Amenomori
We propose to build a large water-Cherenkov-type muon-detector array (Tibet MD array) around the 37,000 m Tibet air shower array (Tibet AS array) already constructed at 4,300…
Anisotropy and Corotation of Galactic Cosmic Rays
gamma Collaboration, M. Amenomori
The intensity of Galactic cosmic rays is nearly isotropic because of the influence of magnetic fields in the Milky Way. Here, we present two-dimensional high-precision anisotropy m…
Observation of PeV Gamma Rays from the Monogem Ring with the Tibet Air Shower Array
The Tibet AS Gamma Collaboration, M. Amenomori
We searched for steady PeV gamma-ray emission from the Monogem ring region with the Tibet air shower array from 1997 February to 2004 October. No evidence for statistically signifi…
Are protons still dominant at the knee of the cosmic-ray energy spectrum?
The Tibet AS Gamma Collaboration, M. Amenomori
A hybrid experiment consisting of emulsion chambers, burst detectors and the Tibet II air-shower array was carried out at Yangbajing (4,300 m a.s.l., 606 g/cm) in Tibet to obta…
