X-Ray Transfocators a Tunable X-Ray Focusing Apparatus Based on Compound Refractive Lenses

Abstract

This paper presents a new generation of ultra-compact and high-vacuum cooled X-ray refractive lens-based transfocators for collimation, transport, and focusing of hard X-rays. The transfocator is an optical device capable of changing the position of focus depending on the number of X-ray refractive lenses, which are exposed along the optical path of X-ray radiation. The design features of the device allow the individual optical elements to be controlled independently of each other, providing a more flexible adjustment of the focal distance for a wide range of applications. The small overall dimensions and light weight of the devices allow them to be integrated into any synchrotron radiation station.
