Follow‐up Observations of Gamma‐ray Bursts with STACEE


STACEE is an atmospheric Cherenkov telescope using the large mirror area of a solar research facility to obtain a low energy threshold. The telescope has a peak in the detected signal of a power‐law gamma‐ray spectrum near 100 GeV. The low energy threshold of STACEE allows detection of gamma rays from higher redshifts than most other ground‐based experiments. The STACEE instrument can be re‐targeted to the position of a GRB within a few minutes of an alert to search for emission above 50 GeV. So far, data have been acquired within a few hours of the burst for five GRB. We discuss the STACEE sensitivity to high energy gamma‐ray emission from GRB and preliminary results of the observations.
