BioCAT undulator beamline at APS
- BioCAT, Argonne National Laboratory, Advanced Photon Source, 9700 S. Cass Ave., Argonne, Illinois60439 (United States)
The Biophysics Collaborative Access Team (BioCAT) project will be an outstanding research facility for biological small angle scattering, non-crystalline diffraction, and x-ray absorption spectroscopy at the Advanced Photon Source, Argonne National Labs. BioCAT operates as an NIH Research Resource under a cooperative agreement with NIH. BioCat has an aggressive program of core and collaborative research, service, and training. Central to the facility is the undulator beam line (designed by G. Rosenbaum, Argonne National Labs) capable of delivering ca. 10{sup 13}{endash}10{sup 14} ph/s to the sample. Focusing optics will allow focal spot ranges from 1.5{times}3.5 mm to 30{times}80 micron, independently adjustable in the vertical and horizontal direction. Up to 8 m camera lengths can be accommodated in the 12m experimental enclosure. The accessible beam energy range will be from 3.5{endash}13 keV using the undulator fundamental and 10{endash}40 keV using the third harmonic. Energy resolution will exceed 2{times}10{sup {minus}4} {Delta}E/E. Detectors will include image plates, CCD detectors and some novel detectors designed to accommodate the high count rates expected at the APS. The multi-element detector will be a very high count-rate (up to 10{sup 9} ph/s global), one dimensional detector optimized for scattering applications. We are also developing a multilayer analyzer detector which maximizes solid angle of collection with high background rejection for biological spectroscopy applications.{copyright} {ital 1997 American Institute of Physics.}
