The Tibet AS experiment successfully detected sub-PeV -rays from the Crab nebula using a Surface Array and underground muon detector. Considering this, we are building in B…
Precision spectral measurements of Chromium and Titanium from 10 to 250 GeV and sub-Iron to Iron ratio with the Calorimetric Electron Telescope on the ISS
O. Adriani, Y. Akaike, K. Asano +77
The Calorimetric Electron Telescope (CALET), in operation on the International Space Station since 2015, collected a large sample of cosmic-ray (CR) iron and sub-iron events over a…
Ground-based Observations of Temporal Variation of Cosmic Ray Spectrum during Forbush Decreases
W. Mitthumsiri, D. Ruffolo, K. Munakata +29
Observations of temporary Forbush decreases (FDs) in the Galactic cosmic ray (GCR) flux due to passage of solar storms are useful for space weather studies and alerts. Here we intr…
