High resolution X-ray spectroscopy and heliography of the sun with rockets
Abstract
A rocket payload is developed for measuring X-ray spectra of the sun with high spatial resolution. The emission lines of highly ionized atoms in the corona are investigated along with the physical processes. Two of the three camera systems are equipped with metal absorption filters. The third employs reflection lattices for spectral fractionation. Wavelengths from 12 to 60 A are measured with a lattice spectrograph in the Rowland rigging, and wavelengths from 10 to 25 A are measured with a crystal spectrometer including four dispersive element crystals and a proportional counter tube as a detector. A method using least squares fit data to center the images and to reduce the zone plate halos is presented.
