RESEARCH INTO THE DESIGN FEATURES OF A HIGH-RESOLUTION ULTRAVIOLET SPECTROSCOPIC SATELLITE.
Abstract
A chronological account is given of the early investigations of a telescopic satellite. This includes a design study contract for an ultraviolet spectrometer, the fabrication of a 32-inch satellite mirror, and steps taken to develop ground-based data handling equipment. During the term of the contract the design study of a highresolution, ultraviolet spectroscopic satellite resulted in the recommendation of a Cassegrain telescope containing a one-meter concave-grating spectrometer. The design of the spectrometer was based on the availability of (1) a uniform and efficient grating, and (2) efficient photomultiplier tubes with highly uniform cathode areas. The purpose of the laboratory-test program at the Princeton University Observatory (PUO) was the selection and testing of gratings and photomultipliers to establish the availability of components with the desired properties.
