PNCSRF Pacific Northwest Consortium Synchrotron Radiation Facility

太平洋西北联盟同步辐射设施(PNCSRF)为来自加拿大各地的科学家提供访问同步辐射光束线、仪器和太平洋西北联盟协作访问小组(PNC-CAT)已经开发并将继续开发的所有技术的机会，作为美国伊利诺伊州阿贡国家实验室高级光子源的重组PNC/XOR(X射线操作和研究)。它允许研究凝聚态物理、表面科学、化学、材料科学、环境科学、地球和地球科学中的广泛问题。X射线技术被用来提取从单晶到液体的有序和无序体系的结构信息。在复杂体系中可以获得配位、物种形成或分布。在微秒到亚纳秒时间尺度上进行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，多极波动装置)光束线和一条弯曲磁铁(BM)光束线。重点是微束和光谱应用，但散射技术是可用的。双晶单色仪可以在2.4keV至75keV的能量范围内以扫描模式工作。光谱技术包括XAFS(XANES和EXAFS)、表面XAFS、DAFS(衍射反常精细结构)和XSW(X射线驻波)。扫描微成像、微XAFS和微衍射可以达到1微米的空间分辨率。X射线散射实验可以用一个、两个、四个和八个圆衍射仪进行。常见的X射线非弹性散射技术包括共振和非共振拉曼散射。外延薄膜原子结构的相干布拉格棒分析(COBRA)是可能的。X射线磁性圆二色谱(XMCD)对磁性的研究是可能的。目前有两种分子束外延(MBE)系统可用于XAFS和表面X射线衍射的原位表征。激光泵浦X射线探测器实验可以使用高重复频率的激光系统发射持续时间为250 ps的脉冲与单个100 ps的x射线光子束同步。

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.
