Fabry-Perot spectroscopy in the far ultraviolet

摘要

The following summarizes the accomplishments and status following the first year of the program 'Fabry-Perot Spectroscopy in the Far Ultraviolet'. In the past year we: completed the design and fabrication of the etalon plates, designed the multilayer coatings for the plates and initiated plans for a mounting assembly of the far ultraviolet Fabry-Perot etalon. The Fabry-Perot etalon that we are building, is being designed to provide reasonably high transmittance at 155 nm (approximately 25), with a spectral resolution of 0.03-0.045 nm over a free spectral range of 0.6-1.0 nm.
