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 Roque de los Muchachos Observatory 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 trigger in the upper atmosphere.
The method is indirect, but offers a much larger collecting area than
is practical with a space mission, which would be necessary to
directly detect the photons of interest.
The dishes are not identical, different subsets covering different
Prototype dishes for the various bands are in operation.
