Pacific Northwest Consortium Synchrotron Radiation Facilility


The PNCSRF provides scientists from across Canada access to the synchrotron radiation beamlines and all the techniques that the PNC/XOR (Pacific Northwest Consortium/ X-ray Operations and Research) has developed and is continuing to develop at the Advanced Photon Source, Argonne National Laboratory, Illinois, U.S.A. The facility at the APS provides a unique, world class, hard x-ray undulator line for high brilliance, high spatial resolution, high energy measurements- over and above what can be performed at the Canadian Light Source.

Experiments can be done by working with current members of the PNCSRF or by a peer-reviewed process for access to either the NSERC share of the PNCSRF beamtime or to the General User program of the APS. Typically 40 distinct users supported by the PNCSRF come to the beamlines each year to conduct experiments. For specific information please contact E. Daryl Crozier (

The PNC/XOR has two fully operational beamlines: an insertion device (ID, multi-pole undulator) beamline and a bending magnet (BM) beamline. Double crystal monochromators can be operated in a scanning mode over the energy range 4.3 keV to 50 kev (ID) and 2.4 to 75 keV (BM). The available instrumentation permits the study of a broad range of problems in condensed matter physics, chemistry, materials science, environmental science, earth and geosciences.

Spectroscopy, microfocussing, elastic and inelastic scattering, molecular beam epitaxy and sub-nanosecond time resolved studies are supported.

  • Spectroscopic techniques include XAFS (XANES and EXAFS), surface XAFS and XSW (X-ray standing wave).
  • Scanning micro-imaging, micro-XAFS and micro-diffraction are routinely done to 1 micron resolution by focusing the x-ray beam with Kirkpatrick-Baez mirrors.
  • Diffraction (elastic scattering) experiments are possible with one, two, four, six and eight circle diffractometers.
  • Resonant inelastic x-ray scattering (RIXS) is done with a wavelength dispersive spectrometer.
  • Momentum-dependent inelastic x-ray scattering (q-IXS) is performed with the LERIX (Lower Energy Resolution Inelastic X-ray scattering) instrument commissioned in 2006.
  • An x-ray waveplate produces adjustable polarization states and permits x-ray magnetic circular dichroism (XMCD) studies of magnetic properties.
  • In situ synchrotron radiation studies of surfaces, interfaces and buried layers. Two UHV chambers can be used to study prepared surfaces, to treat samples in a UHV environment prior to study, or to grow films by molecular beam epitaxy. Samples can be characterized by polarization-dependent XAFS, XSW, specular and diffuse x-ray reflectivity, and surface x-ray diffraction measurements.
  • Sub-nanosecond time resolved laser pump x-ray probe experiments are done on the ID line with a high repetition rate laser system emitting pulses of 200 fs duration synchronized to a single 100 ps bunch of the APS x-ray photons.
  • Time-resolved x-ray excited optical luminescence (TRXEOL) is being developed on the BM beamline. The technique is element, site, excitation channel, and time specific.
