AGASA (Akeno Giant Air Shower Array)

AGASA:

We constructed a very large surface array at the Akeno Observatory (35o 47' N, 138o 30' E) to study origin of extremely high energy cosmic rays. This array is called the Akeno Giant Air Shower Array (AGASA) . AGASA covers an area of about 100 km2 and consists of 111 detectors on the ground (surface detectors) and 27 detectors under absorbers (muon detectors). Each surface detector is placed with a nearest-neighbor separation of about 1 km and the detectors are sequentially connected with a pair of optical fibers. All detectors are controlled and operated by a set of commands transmitted from a central computer.
