As a small spot X-ray monochromator
, the instrument provides better energy resolution than those operating only in the large spot mode.
As a small spot x-ray monochromator
, the XR5 is said to provide better energy resolution than those operating only in the large spot mode.
By combining a large x-ray monochromator
with a water-cooled rotating anode for the x-ray source and a line-imaging detection system, we have dramatically improved the resolution, signal-to-noise ratio, and speed of analysis for the ESCA (electron spectroscopy for chemical analysis) technique (see accompanying box).
Very recently ultra-high resolution X-ray monochromators
have been developed to provide sufficient flux in a narrow band width (5 meV at 14.4 ke V) in order to enable spectroscopy of nuclear energy levels (Mossbauer).
