Design concepts for the Cherenkov Telescope Array CTA: an advanced facility for ground-based high-energy gamma-ray astronomy
Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray astronomy has a huge potential in astrophysics, particle physics and cosmology. CTA is an international initiative to build the next generation instrument, with a factor of 5–10 improvement in sensitivity in the 100 ...
متن کاملThe MAGIC Cherenkov Telescope for gamma ray astronomy
The Major Atmospheric Gamma ray Imaging Cherenkov Telescope (MAGIC) is in commissioning phase and will start to become fully operative by the end of 2003. Located at El Roque de los Muchachos in La Palma (Canary Islands, Spain), it has the largest reflector area (17 m diameter) of all the existing Cherenkov telescopes. New technologies have been used to reduce the energy threshold for gamma-ray...
متن کاملA focusing telescope for gamma-ray astronomy
With the development of the Laue Lens, gamma-ray astronomy is presently realizing the step that virtually all branches of astronomy have accomplished since Lippershey’s invention 400 years ago: the focusing telescope. In a Laue lens, gamma-rays interact coherently inside a crystal via Bragg-diffraction; a large number of diffraction crystals are oriented in a way to deviate incident photons ont...
متن کاملThe Atmospheric Cherenkov Imaging Technique for Very High Energy Gamma-ray Astronomy
One of the last frontiers of the gamma-ray sky is that characterized by the distribution of TeV photons. These photons can be detected relatively easily with ground-based detectors (constituting a TeV ”window” in the atmosphere) and thus the detection of sources did not have to await the availability of space platforms. In practice although the technology was available at an early date, it requ...
متن کاملThe Cat Imaging Telescope for Very-high-energy Gamma-ray Astronomy
The CAT (Cherenkov Array at Th emis) imaging telescope, equipped with a very-high-deenition camera (546 fast phototubes with 0:12 spacing surrounded by 54 larger tubes in two guard rings) started operation in Autumn 1996 on the site of the former solar plant Th emis (France). Using the atmospheric Cherenkov technique, it detects and identiies very high energy-rays in the range 250 GeV to a few ...
