Abstract
The Whipple Observatory gamma‐ray telescope has a high sensitivity to sources of gamma rays in the 0.4 to 4 TeV energy range. Although this sensitivity is used primarily to search for discrete sources of gamma‐rays the instrument also has sensitivity to gamma‐ray bursts on time‐scales from milliseconds to seconds. The field of view is limited but the source location capability is good. Such bursts could radiate with peak luminosity at TeV energies and could originate from(a) primordial black holes or (b) cosmic strings; they could also be the high energy counterparts of BATSE‐type bursts and hence of unknown origin. The search of the Whipple data‐base for statistically unlikely consecutive events on time‐scales of second will be described and compared with the theoretical predictions.
