very-high-energy gamma rays
(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 100 GeV to 100 TeV 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 (Cherenkov detectors).
The gamma rays are of interest
because they are assumed to travel very straight,
increasing the chances of identifying the source.
The term VHE is also used more generally
for this energy range.
Photons beyond 100 TeV are termed ultra-high-energy gamma rays.
