Abstract
A lithium-drifted silicon detector, employing pinhole collimation and mounted on an optical bench for alignment, was used as a nondispersive spectrometer. Developmental studies were conducted for the purpose of evaluating instrument performance, and the techniques evolved were tested. Spectral analysis was accomplished with a computer processing link to effect energy corrections, normalize spectra, smooth data, and produce a graphic output. Two diagnostic units calibrated with identical techniques but having widely divergent imaging properties were compared, and the reasons for their different performances were evaluated as a function of their spectral emissions.
