A PROGRAM OF BASIC RESEARCH TO STUDY X-RAY SPECTRA IN THE REGION 15TO 50 ANGSTROMS

Abstract

Performance tests were completed on a vacuum spectrographic system. High-intensity X-ray excitation was found to produce low working intensities, and was not useful in the detection and analysis of low energy X-rays. Electron excitation provided satisfactory intensities, and made possible the measurement of radiation as 'soft' as carbon (44A), as well as the L series spectra from transitional elements. A wave length shift in the L alpha line was observed between metallic iron and iron in the form of the oxide. A Bendix M-304 detector was studied and found to give non-proportional response to incident photon energy, but it did maintain a low noise level. (Author)
