摘要

The Pacific Northwest Consortium Collaborative Access Team (PNC-CAT) is constructing bending magnet and insertion device (ID) beamlines at the Advanced Photon Source. Both beamlines will be heavily used for XAFS and micro-XAFS experiments. This paper summarises their capabilities, and initial operational experience with the ID line. The ID beamline is based on APS undulator A, and has been running in an initial commissioning configuration since May 1997. Currently the undulator and monochromator energies can be scanned in synchrony for EXAFS measurements, and we have obtained focused beams as small as 0.7 micron using tapered capillaries. Initial testing has also begun on a MBE/UHV system for in-situ surface XAFS.
