Atmospheric Cherenkov experiments

Telescopes and telescope systems:

• CANGAROO at Woomera, Australia [Collaboration between Australia and Nippon for a Gamma Ray Observatory in the Outback]. See also the Australian page from Adelaide.
• CANGAROO-III system of four 10 m telescopes in Australia (fully operational since March 2004).
• CAT  [Cherenkov Array at Thémis]
• CLUE [C(h)erenkov Light Ultraviolet Experiment] at the HEGRA site on La Palma (operational from 1997 to 2000)
• HEGRA Cherenkov Telescopes on La Palma, Canary Islands (operational until Sep. 2002)
• H.E.S.S. [High Energy Stereoscopic System], four 13 m telescopes in Namibia (see also pages from Paris, fully operational since December 2003)
• MACE [Major Atmospheric Cerenkov Telescope Experiment] (project in India)
• MAGIC (a 17 m telescope on La Palma, Canary Islands, operational since 2003)
• University of Durham (operational until March 2000)
• PACT [Pachmarhi Array of C(h)erenkov telescopes] at the High Energy Gamma Ray Observatory at Pachmarhi, India
• TACTIC [TeV Atmospheric Cerenkov Telescope with Imaging Camera] at Mt. Abu, Rajasthan, India.
• VERITAS [Very Energetic Radiation Imaging Telescope Array System] (under construction in Arizona, USA)
• Whipple Gamma-Ray Telescope on Mt. Hopkins, Arizona

Solar power facilities as light collectors:

• CACTUS [Converted Atmospheric Cherenkov Telescope Using Solar-2] (Initially called Solar Two Observatory.)
• CELESTE [CErenkov Low Energy Sampling and Timing Experiment] at Thémis, France
• GRAAL [Gamma-Ray Astronomy at ALmeria] near Almeria, Spain (operational 1998-2001)
• STACEE [Solar Tower Air Cherenkov Experiment] at Sandia Labs, New Mexico

Cherenkov counter arrays:

• AIROBICC (non-imaging counters in the HEGRA array)
• BLANCA [Broad LAteral Non-imaging C(h)erenkov Array] (at CASA), see paper)
• TUNKA-25 (array of non-imaging counters near Lake Baikal)

Other Cherenkov light detection concepts:

• SPHERE (a balloon project looking for light reflected on snow) (link not operational)
• GAW Gamma Air Watch (a project using Fresnel lenses for imaging).

Space Experiments:

•  FGST [Fermi Gamma ray Space Telescope] (see also: Stanford page)]

Future projects:

• CTA [Cherenkov Telescope Array] (a project taking Cherenkov telescope arrays to a larger scale).
