Description
New ultimate parameters of the beam provided by the diffraction-limited sources will open up unique opportunities to build up a new concept for the beam- transport and conditioning systems based on in-line refractive optics [1]. Taking an advantage of the reduced horizontal source size and divergence, the refractive optics integrated into the front-end can transfer the photon beam almost without losses from the source directly to the end-stations. In this regard, development of diamond refractive optics is crucial [2,3]. In addition to traditional focusing applications, the refractive optics can provide the various beam conditioning functions in the energy range from 3 to 200 keV: condensers, micro-radian collimators, low-band pass filters, high harmonics rejecters [4], beam-shaping elements [5].
The implementation of the lens-based beam transport concept can significantly simplify the layout of majority of new beamlines, opening novel opportunities for the protein crystallography [6] and for the material science research under extreme conditions [7-8]. The versatile beam conditioning properties of refractive optics enable to develop and implement new X-ray coherence-related techniques including interferometry [9-11], phase contrast imaging [12-14] and dark field microscopy [15] using light polymer micro-objectives made by additive technology [16].
