Internally cooled V-shape inclined monochromator

P. Oberta, V. Ác and J. Hrdý

Abstract: A simple variant of a Si internally cooled inclined X-ray monochromator of reasonable size is proposed. It has two inclined surfaces oriented into a V shape. This design substantially decreases the surface deformations introduced by radiation heat, and the size of the crystal is still feasible for a 50 mm broad impinging bending magnet or wiggler beam. The possibility of sagittal focusing of the diffracted beam is also discussed.

Keywords: inclined monochromator; heat load; internal cooling.
