DTIC AD0773943: Radiometric Comparison of a Cavity

More Book Details

Description of the Book:

An attempt was made to confirm the calculated value of emitted radiant power from a cavity radiation source by measuring it with a self- calibrated cryogenic bolometer. The measurement was done in high vacuum with 40K surroundings and a nominal radiant power of five nonowatts. Confirmation was not obtained because the self-calibrated bolometer could not be used as an absolute radiometer. However, the comparison effort led to improvements in the source of the radiation and to a better understanding of the bolometer
