Phase-space matching between bent-Laue and flat-Bragg crystals

Conditions for phase-space matching between a bent-Laue crystal and a flat-Bragg crystal, and between a double bent-Laue monochromator and a flat-Bragg crystal, are derived. The concept of phase-space manipulation via a bent-Laue crystal is introduced and applied to practical examples of phase-contrast X-ray imaging.

On the advantages of operation in second-order diffraction of blazed gratings in soft X-ray monochromators

It is shown that the operation of second-order diffraction in blazed gratings with smaller groove densities for the soft X-ray range can be used for scanning to higher photon energies, which might otherwise not be available or may require the use of a higher-density grating.

High-pressure nuclear inelastic scattering with backscattering monochromatization

A capability to perform high-pressure low-temperature nuclear inelastic scattering with a sapphire backscattering monochromator is reported, and it is applied to obtain the density of phonon states of TeO2 at pressures up to 10 GPa and temperatures down to 25 K.

A micro channel-cut crystal X-ray monochromator for a self-seeded hard X-ray free-electron laser

A channel-cut Si(111) crystal X-ray monochromator with a channel width of 90 µm was developed for achieving reflection self-seeding in hard X-ray free-electron lasers. A high conversion efficiency of a monochromatic seed from a broadband X-ray beam was experimentally evaluated to be 2 × 10–2 with a small optical delay of 119 fs at 10 keV.

Soldering of silicon to Invar for double-crystal monochromators

An investigation of the soldering of silicon to Invar using tin alloys for double-crystal monochromators is presented.

Linear array detector for online diagnostics of spectral distributions at MHz repetition rates

The novel line detector KALYPSO has been developed for the measurement of one-dimensional profiles at high-repetition-rate free-electron lasers (FELs) and synchrotron radiation facilities. The current version has 256 pixels with a continuous data readout at a maximum frame rate of 2.7 MHz. At FLASH, KALYPSO has been utilized as photon diagnostics for monitoring pulse-resolved FEL spectra at a repetition rate of 1.0 MHz. KALYPSO is a collaborative effort between the Karlsruhe Institute of Technology (KIT), Paul Scherrer Institut (PSI), Lodz University of Technology (TUL-DMCS) and Deutsches Elektronen-Synchrotron (DESY).

A versatile nanoreactor for complementary in situ X-ray and electron microscopy studies in catalysis and materials science

A series of nanoreactors have been developed for complementary in situ X-ray and electron microscopy. The setup was utilized to monitor thermal annealing processes of porous materials under controlled atmospheres with hard X-ray ptychography.
