Chu², Juan Zhou², Evgeny Nazaretski², Hanfei Yan², Xiaojing Huang² ¹APS, Argonne National Laboratory, USA, ²NSLS-II, Brookhaven National Laboratory, USA	Multilayer Laue lens have been produced with a new material system of WSi2/Al-Si and reach 102 µm in deposition thickness, the largest MLL reported. Also, efficiency measurements of a series of wedged MLLs are presented.
14:00	14:15	XOPT10-2	A tender X-ray PGM for tuning the photon energy interval 0.6 – 6 keV with a single plane grating	Werner Jark Elettra – Sincrotrone Trieste, Italy	A tender X-ray PGM for tuning 600 – 6000 eV
14:15	14:30	XOPT10-3	Soft X-Ray and EUV diffraction gratings design for space and synchrotron applications	Arnaud COTEL HORIBA Scientific, France	The holographic recording technique coupled with the ion-etching process allow to achieve very high groove density up to ~6000gr/mm optimized in EUV and Soft X-Ray. We will describe the method for grating optimization.
14:30	14:45	XOPT10-4	Fabrication of novel gratings to improve spatial resolution in X-ray phase imaging	Talgat Mamyrbayev¹, Katsumasa Ikematsu^{1, 2}, Pascal Meyer¹, Marcus Zuber³, Angelica Cecilia³, Atsushi Momose², Juergen Mohr¹ ¹Institute of Microstructure Technology, Karlsruhe Institute of Technology, Germany, ²Tohoku University, Japan, ³Institute for Photon Science and Synchrotron Radiation, Karlsruhe Institute of Technology, Germany	The spatial resolution of X-ray grating interferometry setups is limited by the gratings period. We have designed and fabricated new parabolic shaped gratings to overcome these limits. Contrast visibility is 80%.
14:45	15:00	XOPT10-5	Multilayer Optics and Scatterless Apertures for High-Brilliance X-ray Sources	Joerg Wiesmann, Frank Hertlein, Jürgen Graf, Carsten Michaelsen Incoatec GmbH, Germany	We discuss multilayer mirrors and scatterless apertures as beam conditioning components in state-of-the-art X-ray analytical equipment for home-labs and synchrotrons. Furthermore, we present applications of these components in combination with high brilliance laboratory microfocus sources.

15:45	16:00	XOPT12-1	X-ray Ring-Focusing Mirror	Hidekazu Mimura¹, Yoko Takeo¹, Hiroto Motoyama¹, Yasunori Senba², Hikaru Kishimoto², Haruhiko Ohashi² ¹The University of Tokyo, Japan, ²Japan Synchrotron Radiation Research Institute, Japan	We propose, fabricate, and evaluate the ring-focusing mirror that can produce the x-ray beam having the ring-shaped intensity distribution. The ring-shaped intensity successfully profiles are observed at the soft x-ray beamline (BL25SU) of SPring-8.
16:00	16:15	XOPT12-2	Ghost Imaging with Paired X-ray Photons	Aviad Schori^{1, 2}, Denis Borodin^{1, 2}, Kenji Tamasaku², Sharon Shwartz^{1, 2} ¹Bar-Ilan University, Israel, ²RIKEN SPring-8 Center, Japan	We observed ghost imaging by using parametrically down-converted x-ray photon pairs. We reconstructed the image of slits with nominally zero background levels. Our procedure can lead to observations of many quantum phenomena at x-ray wavelengths.
16:15	16:30	XOPT12-3	Evidence for collective nonlinear interactions in x ray into ultraviolet parametric down conversion	Denis Borodin¹, Aviad Schori¹, Jean-Pascal Rueff², James Ablett², Sharon Shwartz¹ ¹Bar Ilan University, Israel, ²Synchrotron SOLEIL, France	We present the observation of the non-monotonic spectral dependence of parametric down conversion of x rays into ultraviolet. We propose a model that includes nonlinear interactions with plasmons, which explains the existence of the resonances.
