The Hard X-ray Nanoprobe Beamline (or Nanoprobe Beamline) is an X-ray microscopy facility incorporating diffraction, fluorescence and full-field imaging capabilities designed and operated by the Center for Nanoscale Materials and the Advanced Photon Source at Sector 26 of the Advanced Photon Source at Argonne National Laboratory. This facility was constructed to probe the nanoscale structure of...
CLÆSS is a general-purpose absorption spectroscopy beamline at the ALBA CELLS Spanish synchrotron. Its optical layout is presented here along with its powerful capabilities for collecting absorption spectra with high signal to noise ratio in an unusually wide energy range (2.4–63.2 keV). Continuous energy scanning for quick scans is available, allowing to collect X-ray absorption near edge stru...
A second beamline, BL 7.2, completely dedicated to beam diagnostics is being installed at the Advanced Light Source (ALS). The design has been optimized for the measurement of the momentum spread and emittance of the stored beam in combination with the existing diagnostic beamline, BL 3.1. A detailed analysis of the experimental error has allowed the definition of the system parameters. The obt...
A message oriented software scheme is used for the SPring-8 beamline control [1]. In the early stage, we developed customized control programs for each beamline. As the number of beamlines increased, however, it became necessary to introduce a general software scheme that could handle the control sequence for every beamline. We developed a new server program, Command Interpreter (CI), as a soft...
The performance of X-ray free-electron laser beamlines may be limited by the angular aperture. Compound refractive lenses (CRLs) can be employed to prefocus the X-ray beam, thereby increasing the beamline transmission. A prefocusing CRL was implemented in the X-ray transport of the Matter under Extreme Conditions Instrument at the Linac Coherent Light Source. A significant improvement in the be...
An infrared beamline has been constructed at the 800 MeV electron storage ring, Aladdin. The beamline is located downstream of a short straight section, where it collects edge radiation produced by electrons exiting and entering the bending magnets at the ends of the straight section. Measurements at wavelengths of 1–5 μm suggest that the edge radiation is brighter than standard synchrotron rad...
The beamline BL43IR at SPring-8 has been constructed as a beamline exclusively dedicated to the infrared spectroscopy. The beamline was designed to make use of infrared synchrotron radiation emitted from a bending magnet of 39.3m bending radius with the acceptance angle of 36.5(H) 12.6(V)mrad and to cover a very wide wavelength range from 500 nm (20,000 cm , 2.5 eV) to 100mm (100 cm , 12.5meV)....
The ID22 beamline is dedicated to hard X-ray microanalysis allowing the combination of fluorescence, spectroscopy, diffraction and tomography techniques in a wide energy range from 6 to 70 keV. The recent installation of an in-vacuum undulator, a new sample stage and the adaptation of various focusing optics has contributed to a great improvement in the capabilities of the beamline, which is no...
Angle dispersive x-ray diffraction (ADXRD) is a basic non destructive tool for the determination of crystal structure. Energy tunability and high flux are added advantages in using synchrotron radiation (SR) source for ADXRD technique. We have installed an ADXRD beamline (BL-12) on Indus-2, the Indian synchrotron source. Indus-2 is a 2.5GeV, 300mA SR source. The beamline consists of a Si (311) ...
An undulator-based beamline was built and commissioned at the National Synchrotron Light Source to provide tunable coherent radiation in the 200-800 eV range. The low emittance of the storage ring means that the undulator source has high brightness so that a large flux of coherent x rays is delivered to experimental stations. The beamline uses a horizontally dispersing bichromator that allows t...
