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 bands. Prototype dishes for the various bands are in operation.
