Interferometric Studies of Barium Release

Abstract

The reduction of the Optical Interferometer Secede II data and the design, construction and testing of a rigid mounting cage, pressure housing and thermal housing for a 150 mm aperture Fabry-Perot interferometer are described. Consultation and assistance were provided to R. D. Hake of S.R.I. in the conversion of the interferometer magnetic tape records to ion radiance as a function of spatial scan position in the barium ion cloud. Optical absorption effects at the ion hyperfine wavelength complicate conversion of radiance to ion (and electron) column content, necessitating a radiation transport calculation. The 150 mm Fabry-Perot components were designed and constructed. The assembled instrument is found to maintain high optical resolution in an environment subject to moderate vibration and accelerations.
