Mission Name: OSO 3This Michigan soft X-ray ion chamber photometer was located in the wheel of the spacecraft. The ion chamber was filled with about one atmosphere of dry nitrogen gas and had a 5-mm thickness aluminum foil window. The detector responded principally to energy in the wavelength range 8-12 A, though there was also a low efficiency of response between 2-5 A. Data generated by the instrument were converted to energy fluxes for the wavelength band 8-12 A under the assumption that the radiation was distributed as in a blackbody curve for 2 x 10E6 K. Reliability of operation was verified by using the sun itself as a standard source. The operation was nominal from launch on March 8, 1967, until tape recorder loss in July 1968.
