Computer Differentiation of dc Soft X‐Ray Appearance Potential Spectra

An alternative method of measuring soft x‐ray appearance potential spectra is presented. In this method no modulation, tuned tank, or lock‐in amplifier are used. Rather, the dc current induced in a simple Park‐Houston type detector is measured and digitized, and the data are placed on paper tape for...

Description
Summary:An alternative method of measuring soft x‐ray appearance potential spectra is presented. In this method no modulation, tuned tank, or lock‐in amplifier are used. Rather, the dc current induced in a simple Park‐Houston type detector is measured and digitized, and the data are placed on paper tape for computer processing and differentiation. The computer differentiated spectra compare favorably with spectra obtained by modulation technique.
