Abstract
The 10 m optical reflector on Mount Hopkins in southern Arizona has been converted to a two dimensional imaging detector using an array of fast phototubes. The images of interest are the Cherenkov light generated by small cosmic ray and gamma ray showers in the earth's atmosphere. Fast digitisation techniques are being used to give a 37 pixel image of each shower (full field of 3.50). Since the showers arrive at random times the camera must be triggered by the light signal. The minimum resolving time (integration time) will be 10 nsec but the camera may also be adapted to study slower pulse phenomena The primary purpose of the camera will be high energy gamma ray astronomy in the 1011-11 eV region.
