Feldman, U

A very high resolution grazing incidence spectrograph and vacuum chamber were attached to the Omega laser facility of the Laboratory for Laser Energetics (LLE), at the University of Rochester. The 3 m (88/sup 0/) grazing incidence grating spectrograph can be used with either of two Bausch and Lomb gold replica gratings. One of the gratings has 1200 lines mm/sup -1/ blazed at 2/sup 0/ 35', and although its wavelength coverage extends to 385 A, the spectrograph is most efficient between 8 A and 130 A. The spectral resolution near 100 A obtained with this configuration is better than 0.03 A. The second grating has 600 lines mm/sup -1/ blazed at 6/sup 0/ 2'.
