High-dynamic-range transmission-mode detection of synchrotron radiation using X-ray excited optical luminescence in diamond
Stanislav Stoupin, Sergey Antipov, Alexander M. Zaitsev
We demonstrate enhancement of X-ray excited optical luminescence in a 100-micron-thick diamond plate by introduction of defect states via electron beam irradiation and subsequent h…
Performance of CVD Diamond Single Crystals as Side-bounce Monochromators in the Laue Geometry at High Photon Energies
S. Stoupin, T. Krawczyk, J. P. C. Ruff +3
We report on performance of chemical vapor deposited (CVD) single crystal diamond plates as side bounce monochromators for high photon energies (~20 keV) in the Laue geome…
Large-surface-area diamond (111) crystal plates for applications in high-heat-load wavefront-preserving x-ray crystal optics
S. Stoupin, S. Antipov, J. E. Butler +2
We report fabrication and results of high-resolution X-ray topography characterization of diamond single crystal plates with a large surface area (1010 mm) and (111) cr…
X-ray-induced photoemission yield for surface studies of solids beyond the photoelectron escape depth
Stanislav Stoupin, Bing Shi, Mikhail Zhernenkov
X-ray-induced photoemission in materials research is commonly acknowledged as a method with a probing depth limited by the escape depth of the photoelectrons. This general statemen…
Single Crystal Diamond Refractive Lens for Focusing of X-rays in Two Dimensions
S. Antipov, S. V. Baryshev, J. E. Butler +3
We report the fabrication and performance evaluation of single crystal diamond refractive x-ray lenses with a paraboloid of rotation form factor for focusing x-rays in two dimensio…
Self-detection of x-ray Fresnel transmissivity using photoelectron-induced gas ionization
Stanislav Stoupin
Electric response of an x-ray mirror enclosed in a gas flow ionization chamber was studied under the conditions of total external reflection for hard x-rays. It is shown that the e…
Flux monitoring hard X-ray optics in a single electrode configuration
Stanislav Stoupin, Bing Shi, John Katsoudas
To explore possibilities for X-ray flux monitoring on optical elements electrical responses of silicon and diamond single crystals and that of an X-ray mirror were studied under ex…
Nanoradian angular stabilization of x-ray optical components
Stanislav Stoupin, Frank Lenkszus, Robert Laird +3
An x-ray free electron laser oscillator (XFELO) has been recently proposed [K. Kim, Y. Shvyd'ko, and S. Reiche, Phys. Rev. Lett. 100, 244802 (2008)]. Angular orientation and positi…
