Upgrade of beamline BL08B at Taiwan Light Source from a photon-BPM to a double-grating SGM beamline.
During the last 20 years, beamline BL08B has been upgraded step by step from a photon beam-position monitor (BPM) to a testing beamline and a single-grating beamline that enables experiments to record X-ray photo-emission spectra (XPS) and X-ray absorption spectra (XAS) for research in solar physics, organic semiconductor materials and spinel oxides, with soft X-ray photon energies in the range...
متن کاملA Fast Monte Carlo Generator for ee + eeX Untagged Experiments*
c We describe for untagged 77 experiments a specific and very fast Monte Carlo based on the Double-Equivalent-Photon Approximation. This generator takes into account the experimental constraints in order to perform approximations involving experimentally unobservable effects and to generate events only within the experimental acceptance. It allows a very fast simulation of the events of any cro...
متن کاملDeterminants of entry exclusion within Eex and TraG are cytoplasmic.
We report here functional and topological analyses of TraG and Eex, the donor and recipient cell inner membrane proteins that mediate entry exclusion in the SXT/R391 family of integrative conjugative elements. We found that the exclusion-determining regions of the Eex variants EexS (SXT) and EexR (R391) are located in distinct yet overlapping regions of the proteins. Unexpectedly, the carboxyl-...
متن کاملDiamond beamline I07: a beamline for surface and interface diffraction
Beamline I07 at Diamond Light Source is dedicated to the study of the structure of surfaces and interfaces for a wide range of sample types, from soft matter to ultrahigh vacuum. The beamline operates in the energy range 8-30 keV and has two endstations. The first houses a 2+3 diffractometer, which acts as a versatile platform for grazing-incidence techniques including surface X-ray diffraction...
متن کاملDouble-grating monochromatic beamline with ultrafast response for FLASH2 at DESY
The preliminary design of a monochromatic beamline for FLASH2 at DESY is presented. The monochromator is tunable in the 50-1000 eV energy range with resolving power higher than 1000 and temporal response below 50 fs over the whole energy range. A time-delay-compensated configuration using the variable-line-spacing monochromator design with two gratings is adopted: the first grating disperses th...
