Abstract

The National Bureau of Standards (NBS) has accepted the responsibility for constructing a new facility for the calibration of radiometric sources used in low background environments. Along with the facility's development, a program has been started to study the long term needs of the calibration community and to develop appropriate new test and measurement procedures. The facility consists of a large (60 cm dia by 152 cm long) vacuum chamber whose inner volume is maintained at temperatures of less than 20 K. The radiometer is separated from the source by an isothermal wall whose temperature is actively controlled. The cryogenic cooling of the vacuum interior is accomplished by a closed cycle helium refrigerator system which also contributes to the vacuum maintenance. The source volume can accept a cubic source of up to 30 cm on a side provided the aperture is suitably located. A research and development project is underway to develop methodology to characterize optical attenuators over many orders of magnitude and over a broad wavelength range.
