Nearly stigmatic toroidal grazing-incidence spectrometer in the 100--300-A range: design
- Department of Engineering and Computer Science, Research Laboratory of Electronics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139 (United States)
We have performed an initial design study on a single-element aberration-corrected holographic toroidal spectrometer for use in diagnosing extreme ultraviolet laser amplifiers that we plan to study as part of our tabletop extreme ultraviolet laser project at MIT. The spectrometer is designed to be 7 m long from source to image with an incidence angle of 80{degree} and a 450-line/mm holographic grating. The instrument is designed to be nearly stigmatic between 100 and 300 A to sufficient precision to allow two-dimensional imaging with a 10-{mu}m resolution. As a spectrometer the ideal resolution (with a zero slit width and a 25-{mu}m spatial resolution at the image) is designed to be {lambda}/{Delta}{lambda} {approx} 5000.
