We plan to construct an atmospheric Cherenkov telescope (ACT) at the south pole to study pulsars and other possible sources of very high energy gamma rays. It is believed that a modest number of such sources may account for the bulk of the cosmic radiation. The ACT is the instrument of choice for gamma ray study in the very high-energy (VHE) range of (1011 < E < 1014 eV). A prototype instrument is scheduled for installation at the pole during the 1989-90 austral summer. The south pole is an ideal location in several respects: (i) the long polar night permits almost continuous observation of a source, up to 400 hours per month, and up to 1700 hours/year; (ii) there is a particularly large concentration of interesting candidate sources at high southern declinations, including the remnant of supernova SN1987a; (iii) the circumpolarity of the sky simplifies data analysis; and (iv) the ACT would also operate in conjunction with the South Polar Air Shower Experiment (SPASE) to provide a comprehensive cosmic gamma ray facility.
