The Pacific Northwest Consortium Synchrotron Radiation Facility (PNCSRF) provides scientists from across Canada access to the synchrotron radiation beamlines, the instrumentation and all the techniques that the Pacific Northwest Consortium Collaborative Access Team (PNC-CAT) has developed and will continue to develop as the reorganized PNC/XOR (x-ray operations and research) at the Advanced Photon Source, Argonne National Laboratory, Illinois, U.S.A. It permits the study of a broad range of problems in condensed matter physics, surface science, chemistry, materials science, environmental science, earth and geosciences. X-ray techniques are used to extract information on the structure of ordered and disordered systems from single crystals to liquids.  Coordination, speciation or distribution can be obtained in complex systems. Time resolved studies on the microsecond to sub-nanosecond time scale are possible. The PNC/XOR has two beamlines operational: an insertion device (ID, multi-pole undulator) beam line and a bending magnet (BM) beamline. Microbeams and spectroscopic applications are emphasized, but scattering techniques are available. Double crystal monochromators can be operated in a scanning mode over the energy range  2.4 keV to 75 keV. Spectroscopic techniques include XAFS (XANES and EXAFS), surface XAFS, DAFS (diffraction anomalous fine structure), and XSW (x-ray standing wave). Scanning micro-imaging, micro-XAFS and micro- diffraction can be done to 1 micron spatial resolution. X-ray scattering experiments are possible with one, two, four, and eight circle diffractometers.  X-ray inelastic scattering techniques include resonant and non-resonant Raman scattering. Coherent Bragg Rod Analysis (COBRA) of the atomic structure of epitaxial films is possible. X-ray magnetic circular dichroism (XMCD) studies of magnetic properties are possible.  Two molecular beam epitaxy (MBE) systems are available for in situ characterization with XAFS and surface x-ray diffraction.  Laser-pump x-ray-probe experiments are possible with a high repetition rate laser system emitting pulses of 250 fs duration synchronized to a single 100 ps bunch of x-ray photons.

太平洋西北联盟同步加速器辐射设施 (PNCSRF) 为来自加拿大各地的科学家提供同步加速器辐射束线、仪器和所有技术，这些技术是太平洋西北联盟协作访问团队 (PNC-CAT) 已经开发的，并将继续开发为阿贡国家先进光子源重组后的 PNC/XOR（X 射线操作和研究） 美国伊利诺伊州实验室。它允许研究凝聚态物理、表面科学、化学、材料科学、环境科学、地球和地球科学等领域的广泛问题。 X 射线技术用于提取从单晶到液体的有序和无序系统结构的信息。  配位、物种形成或分布可以在复杂的系统中获得。微秒到亚纳秒时间尺度的时间分辨研究是可能的。 PNC/XOR 有两条可运行的光束线：一条插入装置（ID，多极波荡器）光束线和一条弯曲磁体 (BM) 光束线。强调了微束和光谱应用，但也可以使用散射技术。双晶单色仪可以在 2.4 keV 至 75 keV 的能量范围内以扫描模式运行。光谱技术包括 XAFS（XANES 和 EXAFS）、表面 XAFS、DAFS（衍射异常精细结构）和 XSW（X 射线驻波）。扫描显微成像、显微 XAFS 和显微衍射可以达到 1 微米的空间分辨率。使用一台、两台、四台和八台圆形衍射仪可以进行 X 射线散射实验。  X射线非弹性散射技术包括共振拉曼散射和非共振拉曼散射。可以对外延膜的原子结构进行相干布拉格棒分析（COBRA）。磁特性的 X 射线磁圆二色性 (XMCD) 研究是可能的。  两种分子束外延 (MBE) 系统可用于通过 XAFS 和表面 X 射线衍射进行原位表征。  激光泵浦 X 射线探针实验可以通过高重复率激光系统发射持续时间为 250 fs 的脉冲，与单个 100 ps 的 X 射线光子束同步。
