Scientific paper

The design of a 2D imaging system for the ground-based detection of very-high-energy (100-100,000-GeV) gamma rays from astronomical sources is examined. The system installed at Whipple Observatory (Fegan et al., 1983) uses a 10-m optical reflector to focus Cerenkov radiation resulting from a gamma-initiated air shower onto an hexagonal array of 37 photomultiplier tubes. A software routine calculates the true direction of the shower from the spot pattern and accepts those showers which can have come from the source being observed. A simulated detector response and a sample graphic are shown.
