Abstract

We describe the design of a novel single element holographic toroidal grating spectrometer that would be nearly stigmatic between 100 - 300 angstroms. The instrument would be 7 meters from source to image, and would have a resolution of about 1 in 6000 for a 25 (mu) pixel size. Spatial resolution on the order of 10 (mu) in 2-D would be possible for a spectrally narrow line, such as that produced in a slow and low-density coronal plasma.
