Scientific paper

It is shown here that searches for high-energy gamma rays using the ground-based Cerenkov-light detectors at Potchefstroom (South Africa) and White Cliff station (Australia) for energies greater than 1 TeV, and using the extensive air shower array at Buckland Park (Australia) for energies above a million GeV, can discover cosmic rays in the SN1987A shell if they are produced inside the shell with luminosity down to 10 to the 39th ergs/s. This can support or reject a very wide class of models of cosmic ray production by supernovae. It is argued that such measurements for SN1987A will be possible during the next 1-2 yr, enough time to move Cerenkov detectors from the Northern to the Southern Hemisphere.
