Paper Abstract

We describe a new sounding rocket payload that has been developed for X-ray spectro-scopic studies of the Solar Corona. The instrument incorporates a grazing incidence Row-land mounted grating spectrograph and an extreme off axis paraboloic sector feed system to isolate regions of the sun of order 1 x 10 arc seconds in size. The focal surface of the spectrograph is shared by photographic and photoelectric detection systems, with the latter serving as a part of the rocket pointing system control loop. Fabrication and alignment of the optical system is based on high precision machining and mechanical metrology techniques. The spectrograph covers the 10 to 50 Angstrom interval and has a resolution of 16 milliangstroms in the current version. Modifications planned for future flights will improve the resolution to around 5 milliangstroms, permitting line widths to be measured. The instrument has been developed under the NASA Contract NAS2-9181 and the Lockheed Independent Research Program.
