Workshop Descriptions
Workshop 1: Making
and Using Very Small X-ray Beams
(G. Ice, organizer), April 15, 1997, 9:00 am-4:00
pm
The brilliance of third-generation synchrotron sources will extend many fields of synchrotron-radiation research to µ3 sample volumes. Indeed, intense micron-scale x-ray beams will be used for analysis of elemental composition, chemistry, atomic structure, microstructure, and defect distributions. In this workshop, recent progress in microbeam forming and microbeam applications will be discussed. Forming methods will include Kirkpatrick-Baez mirrors, zone plates, Bragg-Fresnel optics, capillaries, and refractive lenses. Applications will include x-ray microfluoresence analysis, x-ray microstrain analysis, x-ray microdiffraction, and x-ray fluorescence microtomography.

Workshop 2:
Macromolecular Crystallography
(A. Howard, organizer), April 15, 1997, 9:00 am-4:00
pm
The Macromolecular Crystallography Workshop will provide an opportunity for experimenters to share information on biophysical techniques that are in use now or are anticipated for use at the APS. The workshop will comprise four sessions: two in the morning and two in the afternoon. The first session will provide updates on the beamline development projects in the five CATs that are doing research in structural biology: BioCARS-CAT, BioCAT, DND-CAT, IMCA-CAT, and SBC-CAT. The second session will cover optics and instrumentation on biological beamlines at the APS, including discussions of monochromator development, focusing, and beamline controls. The third session will be concerned with advances in experimental techniques at the APS and at similar facilities elsewhere, including sample cooling, multiwavelength anomalous diffraction, sub-microsecond Laue crystallography, and handling of biohazards. The final session will be an opportunity for users to present results of structural biology experiments performed on APS beamlines. Invited talks will be included in the first three sessions, but other submissions for talks are sought for all the sessions except the first. Please contact Andy Howard (ahoward@psyche.csrri.iit.edu) for more information.

Workshop 3: Surface,
Interface, and Thin-Film X-ray Scattering
(M. Bedzyk, organizer), April 15, 1997, 9:00
am-noon
The workshop will concentrate on phenomenological descriptions of x-ray techniques used for studies of surfaces, interfaces, and thin films. Particular emphasis will be placed on describing what is to be gained with 2D-scattering, reflectivity, and standing wave experiments at third-generation SXR undulator beamlines.

Workshop 4: X-ray
Scattering Spectroscopies
(E. Isaacs, organizer), April 15, 1997, 9:00 am-noon
State-of-the-art x-ray optics on high-brilliance synchrotron sources is opening a new frontier in the use of inelastic scattering to probe sub-eV excitations in simple and complex solids and liquids. The excitation energies of interest range from the milli-eV scales associated, for example, with vibrational modes in liquids, to fractions of an eV associated with the excitations of valence electrons in solids. This workshop will include discussions of the x-ray scattering probes, such as nuclear resonance and x-ray Raman scattering, appropriate for the different energy scales. In addition, the workshop will give an overview of some of the interesting excitations that are now becoming feasible to study at the high-brilliance sources.

Workshop 5:
Introduction to the APS
(S. Sinha, organizer), April 15, 1997, 1:30-4:00
pm
This workshop is intended primarily for nonspecialists in synchrotron radiation, i.e., researchers who are interested in learning about the kinds of science they can pursue at the APS and about the unique capabilities of the facility. An overview lecture will describe the properties of APS radiation and present and future applications in areas such as microdiffraction, microscopy, magnetism, spectroscopy, diffraction, and inelastic scattering. Additional lectures will describe the use of the APS for some or all of the following: crystallography, industrial and environmental sciences, materials research, time-dependent scattering, and surface science.

Time-Resolved X-ray Techniques
(S. Dierker, organizer), April 15, 1997, 1:00-4:00
pm
The enormous increase in brilliance of third-generation synchrotron sources, such as the APS, has dramatically increased capabilities for the extension of static x-ray techniques into the time domain. This workshop will explore recent developments in a variety of fields utilizing time-resolved x-ray scattering. Topics to be covered include x-ray photon correlation spectroscopy, time-resolved studies of material kinetics, the use of ultrafast lasers in pump-probe x-ray experiments, and ultrahigh time-resolution x-ray streak cameras.
