“…X-ray topography studies of state-of-the-art HPHT diamond crystals combined with high-resolution X-ray diffraction measurements [2,4,5,6,17,28,29,23] suggest that the portion of a diamond crystal of various orientation originating from the (001) growth sector represents the optimal working region for diamond X-ray optics. Thus, crystals with surface orientation close to (001) have the largest defect-free working regions.…”

The most common applications of diamond crystals in X-ray optics are high-heat-load monochromators for synchrotron beamlines and phase retarders for polarization control. Here, less common applications of diamond at the frontier of X-ray crystal optics are reviewed and summarized. These include a sub-meV-bandwidth X-ray monochromator with high spectral efficiency [1] and all-diamond optical assemblies for beam-multiplexing doublecrystal monochromator at the Linac Coherent Light Source [2]. Also, novel applications for the realization of fully coherent hard X-ray sources are discussed, such as, diamond crystal optics for self-seeding of hard X-rays in the Linac Coherent Light Source [3,4] and Bragg mirrors for the highly anticipated X-ray free-electron laser oscillator [5,6]. These examples present diamond as a material for the next generation of X-ray optics, optics which can provide unique characteristics and capabilities to modern X-ray sources. In addition, details of practical importance on fabrication and characterization methods of diamond crystals with the suitable quality are presented.

“…As such, the use of diamond would always be preferred, were it not for the fact that high-quality thin diamonds of sufficient size with a lattice orientation other than h100i growth direction have historically been extremely difficult to acquire. Only recently did such diamond samples become more available because of significant progress in diamond growth and polishing techniques (Blank et al, 2007;Burns et al, 2009;Shvyd'ko et al, 2010Shvyd'ko et al, , 2011Polyakov et al, 2011;Sumiya & Tamasaku, 2012;Stoupin et al, 2013).…”

Multiplexing of the Linac Coherent Light Source beam was demonstrated for hard X-rays by spectral division using a near-perfect diamond thin-crystal monochromator operating in the Bragg geometry. The wavefront and coherence properties of both the reflected and transmitted beams were well preserved, thus allowing simultaneous measurements at two separate instruments. In this report, the structure determination of a prototypical protein was performed using serial femtosecond crystallography simultaneously with a femtosecond time-resolved XANES studies of photoexcited spin transition dynamics in an iron spincrossover system. The results of both experiments using the multiplexed beams are similar to those obtained separately, using a dedicated beam, with no significant differences in quality.

“…Recent improvements in High Pressure High-Temperature (HPHT) synthesis processes have shown promising results in improved crystal quality. [24][25][26][27][28][29] A set of diamond crystals of the (111) orientation, mounted on an all-diamond mounting frame assembly, was prepared by the Technological Institute for Superhard and Novel Carbon Materials (TISNCM, Troisk, Russia). They were characterized and optimized at the Advanced Photon Source (APS, Argonne, IL) by high resolution topography and then installed in the XPP LODCM for splitting the FEL beam.…”

A double-crystal diamond monochromator was recently implemented at the Linac Coherent Light Source. It enables splitting pulses generated by the free electron laser in the hard x-ray regime and thus allows the simultaneous operations of two instruments. Both monochromator crystals are High-Pressure High-Temperature grown type-IIa diamond crystal plates with the (111) orientation. The first crystal has a thickness of ∼100 μm to allow high reflectivity within the Bragg bandwidth and good transmission for the other wavelengths for downstream use. The second crystal is about 300 μm thick and makes the exit beam of the monochromator parallel to the incoming beam with an offset of 600 mm. Here we present details on the monochromator design and its performance.
