A program at NBS leading to the realization of practical, stable transfer detector standards for the far ultraviolet is reviewed. Three basic detector types, one covering the region of 584-1216 A and the other two covering the region of 1164-2537 A, are described. Examples of these detectors have been calibrated at NBS and distributed to laboratories throughout the United States and Europe, where they are being used as primary radiometric calibration references in a variety of far-uv experiments.
Canfield et al. (1973) studied this question.
