The Wide-field Infrared Survey Explorer (WISE) is a NASA MidEx mission which will survey the entire sky at 3.3, 4.7, 12 and 23 microns. As with most all-sky surveys, WISE results will address many fundamental topics, but the passbands and sensitivity are particularly well suited to study the distribution and evolutionary history of brown dwarfs and ultra-luminous IR galaxies. The two long wavelength bands will use 1024×1024 Si:As BIB detectors manufactured by DRS Sensors & Targeting Systems. NASA ARC has optimized the operating parameters as well as conducted detailed cryogenic performance and radiation testing of a prototype array. Dark current, noise performance, and radiation test results will be reported.
