Abstract

The use of photographic emulsions in several rocket-borne instruments for the study of the solar X-ray emission has led to a programme of laboratory studies of four high-speed X-ray films. Results are given for the absolute photon sensitivities of commerciail lford Industrial X-ray film, type G, a single layer unsuper; coated IIford Industrial G, unsupercoated Kodirex, and Kodak-Pathé-SC5, over the wavelength range 2-14-5 Å. The precision and repeatability of calibration for a given batch of film are discussed. Measurements of the inherent grain photon equivalence for two emulsions are also given. No significant exposure temperature coefficient is found for the IIford and centrifuged Kodak emulsions over the range 20-78°C.
