Abstract:

A vacuum spectrograph and pumping station have been purchased and installed in the Intense Beam Interaction Laboratory at the University of Michigan. Specifically, an Acton Research Corporation Model VM-510 1.0 meter, f8.7 corrected Czerny-Turner vacuum monochromator with turbo-molecular pump and three gratings 1 1200 gmm plane ruled blazed at 500 nm, 2 1200 gmm plane ruled blazed at 200 nm and 3 600 gmm plane ruled blazed at 400 nm. This instrument has been tested and has been used to obtain data on several research projects. This instrument is being used to study population inversions in ablation plasmas generated by long pulse, intense, relativistic electron beams, a project currently supported by the Air Force Office of Scientific Research AFOSR 86-0012. Keywords Vacuum spectrograph.
