Title: A New XAFS Beamline NW10A at the Photon Factory

Abstract

A new XAFS beamline NW10A using bending magnet radiation from 6.5 GeV PF-AR has been constructed. NW10A consists of a Si(311) double crystal monochromator and a Pt-coated bent cylindrical focusing mirror and provides focused X-ray beam between 8 and 42 keV. The obtained flux through a 1mm square slit is 1x1010 ph/s at 20 keV and 7x109 ph/s at 30keV, which are 20 and 200 times more intense than obtained at BL-10B. Platinum K-edges do not degrade the quality of XAFS spectra when higher orders are properly reduced. High quality Ce K-edge XAFS spectra are easily obtained.

  • A new VUV beamline at the Photon Factory ring that is designed to accept radiation emitted from an undulator is described. The characteristics of the undulator and all parts of the beamline; a front end, a mirror system, and two monochromators, are described in detail. The characteristics of optical elements in the beamline are also shown.
  • Design and experience of the initial operation of a new beamline (BL-16) for a 3.6-m-long, 53-pole wiggler/undulator constructed at the Photon Factory are described. The insertion device has hybrid permanent magnets with a period of 12 cm and a maximum magnetic field of 1.47 T. In the undulator mode, the energy of the fundamental peak can be varied from 40 to 400 eV. In the wiggler mode, an x-ray beam (critical energy of 6 keV) 50--100 times more intense than that from the bending magnets is obtained. The beamline consists of two time-shared branch lines: a side beamline for softmore » x-rays in the undulator operation, to which photon beams are deflected sideways by a cylindrical SiC mirror, and a straight line for hard x rays under the wiggler operation. On the hard x-ray line, a fixed-exit sagittal-focusing double-crystal monochromator has been installed and commissioned. Collimating and refocusing mirrors will be installed in 1989. On the undulator beamline, a soft x-ray monochromator utilizing sophisticatedly devised aberration correction optics is commissioned.« less
  • Recent advances in high-throughput techniques for macromolecular crystallography have highlighted the importance of structure-based drug design (SBDD), and the demand for synchrotron use by pharmaceutical researchers has increased. Thus, in collaboration with Astellas Pharma Inc., we have constructed a new high-throughput macromolecular crystallography beamline, AR-NE3A, which is dedicated to SBDD. At AR-NE3A, a photon flux up to three times higher than those at existing high-throughput beams at the Photon Factory, AR-NW12A and BL-5A, can be realized at the same sample positions. Installed in the experimental hutch are a high-precision diffractometer, fast-readout, high-gain CCD detector, and sample exchange robot capable ofmore » handling more than two hundred cryo-cooled samples stored in a Dewar. To facilitate high-throughput data collection required for pharmaceutical research, fully automated data collection and processing systems have been developed. Thus, sample exchange, centering, data collection, and data processing are automatically carried out based on the user's pre-defined schedule. Although Astellas Pharma Inc. has a priority access to AR-NE3A, the remaining beam time is allocated to general academic and other industrial users.« less
  • A planar undulator beamline, BL-13A, covering 30-1,000 eV has been constructed in the Photon Factory. The main scientific targets are investigations of organic thin films and biomolecules adsorbed on well-defined surfaces using angle-resolved photoelectron spectroscopy, X-ray photoelectron spectroscopy, and X-ray absorption spectroscopy. A variable-included-angle Monk-Gillieson mounting monochromator with varied-line-spacing plane gratings is used to achieve a high photon flux of 10{sup 10}-10{sup 12} photons/s with a high resolution (E/{Delta}E) of 7,000-30,000. A typical spot size on the sample position is estimated to be 130 {mu}m (horizontal)x40 {mu}m (vertical). After commissioning, BL-13A will be open for users from January 2010.
  • A XAFS-experiment allowing for in-situ experiments has been set up at DORIS bending magnet beamline C. For that purpose, a new double-crystal, UHV-compatible monochromator with fast scanning capability was designed. This fixed-exit monochromator uses two crystal sets on a common central rotation axis driven by an ex-vacuo goniometer. Bragg angles range from 5 deg. to 55.5 deg. resulting in a total energy range 2.3 - 43.4 keV using Si(111)/(311) crystal sets. Crystal pairs can be remotely selected by translating the vacuum chamber. Energy encoding is performed using an optical encoder system. The standard XAFS sample environment is set-up in vacuomore » and can be adapted for special sample environments. For in-situ experiments, the beamline is equipped with twelve gas lines. An exhaust line allows toxic/reactive gases to be handled. As an initial performance test of the instrument, Ti, Cr, Fe and Cu XAFS and Ce K-shell QEXAFS measurements were performed.« less
