Title: The Design and Performance of Beamline BL15 at SAGA Light Source

Abstract

A new X-ray beamline has been designed and constructed at SAGA Light Source. The beamline, named BL15, covers an energy range from 2.1 to 14.2 keV and is intended for the characterization of various materials developed for industrial purposes. The beamline has an experimental station for the performance of several experiments: e.g. X-ray absorption fine structure (XAFS) measurement; high resolution diffractometry; topographic imaging; energy-dispersive four-circle diffractometry. The photon flux passing through a receiving slit at XAFS measurement position is more than 1 x 1011 photons/sec with focusing mirror in the energy range of less than 8keV. The XANES spectra measurements of Cu and Ti K-edge show that the beamline has a good energy resolution.

  • Saga Light Source (SAGA-LS), which has been constructed at Tosu city in Saga prefecture, is a compact synchrotron light source with storage electron energy of 1.4 GeV. A new beamline for the development of advanced materials and processing has been designed, and is now under construction at BL9 of SAGA-LS. This beamline is one of the three bending magnet beamlines (BL9, BL12, and BL15) constructed by Saga Prefectural Government. In this paper, we describe the design and the expected optical performance of the beamline BL9 at SAGA-LS.
  • A new hard X-ray beamline, BL15, has been designed and constructed at the SAGA-Light Source. The beamline is optimized for industrial applications of the synchrotron light. X-rays with photon energies from 2.1 keV to 14.2 keV are delivered to the experimental station passing a fixed-exit double-crystal Si(111) monochromator and a bent cylindrical mirror. Basic experimental equipments for XAFS measurement, high resolution diffractometry, various kinds of X-ray imaging and energy-dispersive diffractometry have been prepared for the station. From our initial commissioning and performance testing of the beamline, we show that BL15 can perform XAFS measurements.
  • A new soft X-ray beamline (BL10) at the SAGA Light Source (SAGA-LS) was constructed at the end of 2008. Commissioning of this new beamline started at the beginning of 2009. Synchrotron radiation from a variably polarizing undulator (APPLE-II) can be used in this beamline. The obtained light is monochromatized by a varied-line-spacing plane grating monochromator with the variable included angle mechanism. Its designed resolving power and photon flux are 3,000-10,000 and 10{sup 12}-10{sup 9} photons/s at 300 mA, respectively. The performance test results were generally satisfactory. An overview of the optical design of the beamline and the current status ofmore » commissioning are reported.« less
  • Phase I of the X21 beamline at the National Synchrotron Light Source was commissioned during 1993. The research program at the X21 beamline is focused on the study of electronic excitations in condensed matter with total energy resolution of 0.1--1.0 eV. The source is a 27-pole hybrid wiggler. A water-cooled horizontal focusing Si(220) monochromator and a spherically bent Si(444) analyzer were installed and commissioned. At 8 keV the energy resolution of the monochromator is about 0.7 eV, and the energy resolution of the analyzer is about 0.1 eV. Results from several selected experiments are also discussed.
  • Bending magnet beamline 9.3.2 at the Advanced Light Source (ALS) was designed for high resolution spectroscopy with the capability for delivering circularly polarized light in the soft x-ray energy region using three gratings. The monochromator is a fixed included-angle spherical grating monochromator (SGM) and was originally used at SSRL as a prototype for later insertion-device-based monochromators for the ALS. For operation at the ALS, the toroidal pre-mirror used at SSRL was replaced by a horizontally focusing and a vertically focusing mirror in the Kirkpatrick-Baez configuration. Circularly polarized radiation is obtained by inserting a water-cooled movable aperture in front of themore » vertically focusing mirror to allow selecting the beam either above or below the horizontal plane. To maintain a stable beam intensity through the entrance slit, the photocurrent signals from the upper and lower jaws of the entrance slit are utilized to set a feedback loop with the vertically deflecting mirror piezoelectric drive. The beamline end station has a movable platform that accommodates two experimental chambers enabling the synchrotron radiation to be directed to either one of the two experimental chambers without breaking the vacuum. {copyright} {ital 1996 American Institute of Physics.}« less
