The Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE) is a ground-based gamma-ray telescope designed to study astrophysical sources of gamma rays in the energy range from 50 to 500 GeV. STACEE uses an array of 64 heliostat mirrors at the National Solar Thermal Test Facility in New Mexico to collect Cherenkov light generated by extended air showers and concentrate it onto cameras composed of photomultiplier tubes. The full STACEE experiment is now complete and started observations in October 2001. The telescope has a lower energy threshold than previous prototype due to superior triggering and electronics, including flash ADCs for every channel. Here we will discuss the performance of the complete instrument and present preliminary results of selected observations.
