ARCADE (Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission) is a balloon-borne cryogenic instrument to measure the spectrum of the cosmic microwave background radiation at centimeter wavelengths. ARCADE compares the sky to an on-board external blackbody target to measure small differences between the sky spectrum and a known blackbody. The instrument uses a novel open-aperture cryogenic design to minimizes sources of systematic error. In particular, there are no windows between the cold (2.7 K) optics and the atmosphere during observations. We discuss the cryogenic performance of ARCADE during its first flight in November 2001.

ARCADE is funded through NASA RTOP 685-344-01-05-01
