摘要

Abstract: We have developed two sources of high flux radiation: one, designated as SPX II, exploits the principle of spherical convergence of a strong shock wave in a noble gas to generate a plasma at the center of a sphere hot enough to emit broadband radiation from the UV to the soft x-ray region of the spectrum; the other is based on the principle of vacuum spark, whereby accelerated electrons in a strong electric field in vacuum bombard an aluminum anode surface, leading to K-alpha line emission (1.7 keV). Typical measured outputs from the SPX II are: 186 W in the visible range (3500 - 2800 angstrom); 754 W in the UV range (2800 - 1800 angstrom); 650 W in the deep UV (1800 - 600 angstrom), and 5 W in the soft x ray (15 - 10 angstrom) for an operating repetition rate of the machine of 1 Hz. Typical measured output from the vacuum spark source is 30 W in the K-alpha line (7 angstrom) for a few kilowatt machine. The above are all powers measured beyond the pertinent filter used to select the radiation of interest, such as beryllium, aluminum, or other filters. !5
