Demonstration of resolving power $\lambda /\Delta \lambda >10,000$ for a space-based x-ray transmission grating spectrometer

Ralf K. Heilmann, Jeffery Kolodziejczak, Alexander R. Bruccoleri +2

We present measurements of the resolving power of a soft x-ray spectrometer consisting of 200 nm-period lightweight, alignment-insensitive critical-angle transmission (CAT) grating…
