Using the UHV experimental endstation on the soft X-ray beamline at the Australian Synchrotron, lysozyme and proteinase K crystals have been exposed to a vacuum of 10-5 mbar, prior to flash-cooling in a bath of liquid nitrogen. Subsequent data collection on the MX2 beamline at the Australian Synchrotron demonstrated that, for lysozyme and proteinase K, it is possible to subject these mounted cr...

232 LLE Review, Volume 76 The near-field intensity modulation due to a diamond-turned KDP wedge is investigated through computer simulations within the framework of its application to LLE’s OMEGA laser system. KDP wedges will be installed on each OMEGA beamline and mounted 12 m away from the final focusing optics. The wedges will improve the direct-drive inertial confinement fusion uniformity b...

A technology center for the production of high-precision reflection gratings has been established. Within this project a new optics beamline and a versatile reflectometer for at-wavelength characterization of UV- and XUV-reflection gratings and other (nano-) optical elements has been set up at BESSY-II. The Plane Grating Monochromator beamline operated in collimated light (c-PGM) is equipped wi...

The X-ray free-electron laser of the Pohang Accelerator Laboratory (PAL-XFEL) was opened to users in 2017. Since then, significant progress has been made PAL-XFEL operation and beamline experiments. This includes increasing FEL pulse energy, photon generating self-seeding FEL, trials two-color operation. In beamline, new instruments or endstations have added are being prepared. Overall, stabili...

Abstract European XFEL is a multi-beamline x-ray free-electron laser (FEL) user facility driven by superconducting accelerator with nominal photon energy range from 250 eV to 25 keV. An afterburner undulator based on technology currently being investigated enable extension of the towards harder x-rays. This would be installed downstream already operating SASE2 FEL beamline, emitting at fundamen...

The XDD beamline (http://ssls.nus.edu.sg/facility/beamlines/xdd/xdd.htm) at SSLS delivers a tunable monochromatized photon source with high resolution in a wide energy range (2.3-10 keV). This hard x-ray light source is ideal for diffractometry, fluorescence detection and absorption spectroscopy, especially the study of XAFS (x-ray absorption fine structure) and XANES ( X-ray Absorption Near Ed...

Nowadays, three-dimensional structure of protein becomes important to understanding and application of molecular mechanisms in enzyme reaction, signal transduction and other various biochemical processes. The amount of the information is now growing quantitatively and qualitatively, supported in part by the technical development of macromolecular crystallography. In the development, brilliant s...

Monte Carlo simulations are being performed to design and characterize the neutron optics components for the two fundamental neutron physics beamlines at the Spallation Neutron Source. Optimization of the cold beamline includes characterization of the guides and benders, the neutron transmission through the 0.89 nm monochromator, and the expected performance of the four time-of-flight choppers....

Abstract The SSRF Phase-II Beamline Project started November 20, 2016 with a 6-year construction period. This project is mainly to construct 18 new beamlines and more than 30 end-stations, as well the corresponding storage ring upgrades, user auxiliary laboratories, beamline technology support infrastructures. Till now, 11 have passed technical acceptance test been in running. remaining seven w...
