Abstract :
SuperCam is a 64-pixel heterodyne imaging array designed for use on ground-based submillimeter telescopes to observe the astrophysically important CO J=3-2 emission line at 345 GHz. Each pixel in the array has its own integrated superconductor-insulator-superconductor (SIS) mixer and low noise amplifier. In spring 2012, SuperCam was installed on the University of Arizona Submillimeter Telescope (SMT) for its first engineering run. SuperCam completed two additional science runs in May 2013 and March 2014. During these science runs, over 80% of the pixels were in operation with a median double sideband receiver temperature of 104 K and an Allan time of ~100 s.
