Solar corona studies using normal-incidence X-ray optics

Abstract

The progress which has been made in constructing a new type of X-ray telescope, which operates at normal incidence in the soft X-ray region by the use of multilayer coatings is described. The principles involved in state-of-the-art multilayer technology and some high-resolution imaging results are discussed. A rocket payload incorporating a multilayer X-ray mirror is presently being constructed. It is of Ritchey-Chretien design and the expected spatial resolution is 1/4 arcsec. The scientific program for solar-coronal studies and future instrumental developments are also discussed.
