Quantative Spectroscopy of X-Ray Laser Plasmas in Pulsed Power Devices

Abstract

This research program designed and constructed a small z-pinch discharge. Some preliminary studies of the discharge were made using a framing camera, a visible spectrometer and a VUV spectrometer. A quadrature interferometer was designed and its constituent parts were procured. Estimates of the electron density obtained side-on, with the interferometer, and end-on, from VUV measurements of line widths, gave n sub e to be at most roughly 10 to the -17th power/cc. In an effort to augment this density and to obtain a more classical type of z-pinch behaviour a second version of the discharge was designed and constructed. A framing camera study of this discharge confirmed the expected behaviour and further demonstrated the presence of an unacceptable degree of cylindrical asymmetry. End-on VUV spectra revealed the absence of all lines below roughly 800 A.
