| Abstract: | We describe a cryogenic blackbody reference, or cold load for millimeter wavelength radiation. This blackbody has an emissivity   0.99 over a two octave wavelength range. We use it as a standard when calibrating sensitive infrared photometers. The particular geometry of the blackbody described is influenced by our application. The basic design data and philosophy are described so that other designs can be evaluated. |
