Abstract
A grazing incidence one‐dimensional focusing collector for use in the extreme ultraviolet is described. The collector has a field of view of 1×50°, a focal length of 3015 cm, and a total unobstructed area of 224 cm2. The instrument employs an interchangeable detector package of either channel‐electron multipliers or proportional counters which yield a limiting sensitivity of 1.0 photons/cm2 sec Å at 170 Å and 0.05 photons/cm2 sec Å at 90 Å, respectively, for one second integrations. The design and calibration of the instrument are described in detail. Data obtained by this instrument during recent rocket flights are presented.Keywords
