Mission Name: OSO 1This experiment, which monitored solar hydrogen Lyman-alpha flux, was mounted in the wheel section of the spacecraft so that it scanned the sun once during every 2-s rotation. The detector was a carbon disulfide-filled ion chamber with a lithium fluoride window that provided a bandpass of 1050 to 1230 A. The overall sensitivity of the detector declined by 80% after 230 orbits, but this decline did not affect short-term relative measurements. Except for the degradation of sensitivity, the experiment performed normally during the life of the spacecraft.
