Abstract：
Data taken with ACT2 and ACT3 betWeen 1995 and 1997 are used to search for 0.1 second bursts of TeV gamma Rays from evaporating Primordial Black Holes (PBHs). There is no evidence for such bursts in the dataset. Using the result,the upper limit of 3 ×10⁸pc^－3yr^－1 on the rate-density of evaporating PBHs is set in the vicinity of the solar system at a 99% confidence level.
