Astrophysics around 100 GeV with STACEE


STACEE is an atmospheric Cherenkov detector using the large mirror area of a solar research facility to obtain an energy threshold around 100 GeV. STACEE has been used to study the Crab and several AGN: Markarian 421, W Comae, H 1426 + 428. The STACEE observing program is coordinated with the high-energy astrophysics community both by participation in multiwavelength campaigns and by follow-up observations of γ-ray burst alerts. Analysis methods under development using pulse height information from flash ADCs installed on each channel are expected to substantially improve the experiment’s sensitivity. A summary of the performance is given.
