Abstract
ECHELLE SPECTROGRAPHS DESIGNED FOR THE VACUUM ULTRAVIOLET HAVE BEEN LIMITED IN THEIR USEFULNESS DUE TO LOW EFFICIENCY AND STRAYLIGHT OF THE ECHELLE GRATING. THIS PROJECT APPLIESNEW APPROACHES IN COATING TECHNOLOGY AS A MEANS TO PROVIDE IMPROVED DEVICES. THE R&D EFFORT INCLUDES THE STUDY OF VACUUM DEPOSITION CONDITIONS AND THEIR RELATIONSHIP TO THE RULEABILITY OF ECHELLE GROOVES. SEVERAL TEST COATINGS WILL BE COMPLETED AND TEST ECHELLES RULED. THESE ECHELLES AND THEIR REPLICAS ARE TESTED FOR EFFICIENCY AND STRAY-LIGHT BETWEEN 1900A AND 3000A. ANY IMPROVEMENT IN EFFICIENCIES OVER 50% WOULD BE CONSIDERED A SUCCESS. IF THE RESEARCH ON THESE COATINGS PROVES TO BE SUCCESSFUL, THE RESULTS COULD DEVELOP THE UNDERSTANDING NEEDED TO IMPROVE ECHELLE GRATING RULING TECHNOLOGY.
