Cherenkov Telescope Array
(ground gamma-ray telescope array in development)
The Cherenkov Telescope Array (CTA)
is a planned for a Cherenkov gamma-ray telescope
consisting of a pair of arrays of ground-based telescopes
on the Atacama Desert in Chile (99 dishes)
and La Palma in the Canary Islands (19 dishes)
for observation of gamma rays.
Their aim is to spot high-energy gamma-ray photons by observing the
Cherenkov radiation they produce in the upper atmosphere.
The method is indirect, but offers a much larger collecting area than
is practical with a space mission, which is what is needed for
the photons of interest.
The dishes are not identical, different subsets covering different
Prototype dishes for the various bands are in operation.
