Using a prism to reject or select harmonic reflections in an X-ray monochromator

Journal of Applied Crystallography, 2000
The angle by which an X-ray deviates from its original direction when it passes through a refractive prism is proportional to the square of the X-ray wavelength. This effect was used to discriminate between different harmonic orders of a two-crystal non-dispersive monochromator. Two cases are discussed.

A Spectrophotometric Study of Ultraviolet and X-ray Sources with Objective Prism Plates

1977
Several objective prism spectra of objects known to have large ultraviolet or X-ray fluxes are discussed. A marked Balmer excess and H alpha emission are found in X Per(= 3U 0352 + 30) and in the similar Be star HD 200775. No Balmer discontinuity is detectable in HD 226868 (Cyg X-1) during the low X-ray states, in HZ 43 (MX 1313 + 29), and in the hot ...
