Very-High-Energy Gamma Rays

(VHEGR)
(energetic gamma rays with 100 GeV to 100 TeV photon energy)

The term Very-High-Energy Gamma Rays (VHEGR) is used for Gamma Rays in the 100GeV to 100TeV range of energy-per-photon. Such high-energy photons are detected, typically with detectors for this specific range that detect Cherenkov Radiation resulting from interaction of the high-energy photon with the Earth's Atmosphere. The gamma rays are of interest because they are assumed to travel very straight, increasing the chances of identifying the source.

Beyond 100TeV is Ultra-High-Energy Gamma Rays (UHEGR).
