MECHANICALLY SIMPLE FLAT-CRYSTAL X-RAY SOURCE/MONOCHROMATOR

摘要

The design of a new type of flat-crystal x-ray source/monochromator is discussed. This new design has many advantages over previous designs. It is extremely easy to construct, compact, and portable. It is easy to align and may be adapted to a wide variety of detectors. Its dispersion crystal is easily changed, allowing the same instrument to be used for a very wide range of wavelengths. For example, with a crystal such as LiF (422) its operating range would be in the tens of kilovolts, whereas with a phthalate crystal its range would be from similar to 900 eV to similar to 3 keV. Furthermore the same instrument can be used with a multilayer to extend its useful range almost down to the vacuum UV. (C) 1996 Optical Society of America [References: 4]
