XRD
W-1 Texture Analysis I (Learning Center)
| Organized by: |
H. Schaeben, Freiberg University
of Mining and Technology, Freiberg, Germany |
| Instructors: |
H. Schaeben, Freiberg University
of Mining and Technology, Freiberg, Germany
R.J. De Angelis, University of Florida, Shalimar, FL
F. Heidelbach, Universität Bayreuth, Bayreuth, Germany
J. Fundenberger, Université de Metz, Metz CEDEX, France |
Identifying experimental pole intensity data with
the result of scanning the spherical X-ray transform
of an orientation density function, a unifying view of
mathematical texture analysis is presented in
terms of spherical tomography. Material science application based
on common X-ray radiation and very
recent geoscience applications based on synchrotron radiation
because of its penetration depth and
angular resolution will be used to explain the rationale of
texture analysis.
W-2 Methods of Phase Identification (Carson)
| Organized by: |
R. Jenkins, Emeritus,
International Centre for Diffraction Data, Newtown Square, PA |
| Instructors: |
R. Jenkins, Emeritus,
International Centre for Diffraction Data, Newtown Square, PA
J. Faber, T. Fawcett, International Centre for Diffraction Data, Newtown
Square, PA |
This workshop is intended for those new to the field of phase
identification by X-ray powder diffraction.
The program is based on the use of many worked examples and
utilizes each of the standard
search/match methods currently supported by the ICDD.
XRF
W-3 Fundamentals of XRF (Summit I & II)
| Organizers & Instructors: |
J. Gilfrich, Emeritus, SFA, Inc./NRL,
Washington, DC
J. Croke, Emeritus, Philips Analytical, Inc., Natick, MA |
This workshop is intended to explain briefly the basics of
X-ray emission and how that information is
applied in the practice of X-ray Fluorescence Analysis. While
aimed at new workers in the field, the level
of detail should have some interest for the more experienced
analyst.
W-4 Analysis of Layered Materials by XRF (Fremont)
| Organized by: |
M.W. Dirken, Philips Analytical,
Almelo, The Netherlands |
| Instructors: |
M.W. Dirken, Philips Analytical,
Almelo, The Netherlands
M. Mantler, Vienna University of Technology, Vienna, Austria
A. Wittkopp, NeXray L.L.C., Ronkonkoma, NY |
This workshop provides an introduction to the analysis of
layered materials and is intended for the
X-ray spectroscopist who encounters this analysis for the first
time. Therefore, the physics and various
analysis models are presented. This is followed by contributions
of ED-XRF and WD-XRF examples,
focusing on practical issues including problems of finite
thickness and line selection.
Workshops, Monday p.m.

Continuation of W-1.
W-6 Advances in Database Technology (Carson)
| Organized by: |
J. Faber, International Centre for
Diffraction Data, Newtown Square, PA |
| Instructors: |
J. Faber, S. Kabekkodu,
International Centre for Diffraction Data, Newtown
Square, PA |
The International Centre for Diffraction Data (ICDD) is
responding to the changing needs in
powder diffraction and materials analysis by developing completely
new Powder Diffraction Files
(PDF-4) in relational database (RDB) format. In this workshop, an
overview of RDB technology will
be presented, and how this technology helps to set the stage for
total pattern analyses. The
PDF-4/Full File 2002 contains 136,895 powder diffraction patterns,
mainly from inorganic phases.
The PDF-4/Organics 2002 will contain approximately 150,000 entries
nearly all of which are organic
phases. On-the-fly fully digitized patterns have been developed to
facilitate direct comparisons
between experiment and reference data in the PDF-4. A number of
specific data mining exercises
that demonstrate the power of a relational database format over
the traditional (flat file) database
structures will be presented. More importantly, it will be
illustrated how these data mining techniques
can be exploited in real problem-solving environments.
XRF
W-7 Specimen Preparation I (Summit I & II)
| Organized by: |
D. Broton, Construction Technology
Labs, Skokie, IL |
| Instructors: |
D. Broton, S. Nettles,
Construction Technology Labs, Skokie, IL
J. Anzelmo, Bruker AXS, Inc., Madison, WI
V. Kocman, A.S.O. Design, Quebec, Canada |
The sampling and specimen preparation workshop at the DXC
continues to be a fundamental
aspect of the Conference. This workshop covers the basics of
sampling and specimen preparation
for a wide variety of materials. Novel approaches to preparing
specimens for analysis come from
instructors with many years of experience applying those
techniques to real-world industrial samples.
Tricks-of-the-trade and useful tips for both novices and
experienced X-ray analysts will be presented.
The audience is encouraged to participate by providing input about
their own experiences, sample
types and solutions. Topics in 2002 will include sampling, pressed
powders, borate fusions, and loose
packed powders. Sample preparation methods for pitch and treated
wood as well as using reference
materials and pure compounds for standardization of XRF
instruments will also be included.
W-8 Polarized X-ray Optics (Summit III)
| Organized by: |
B. Chappell, Macquarie University,
Sydney, Australia |
| Instructors: |
B. Chappell, Macquarie University,
Sydney, Australia
R.W. Ryon, Emeritus, Lawrence Livermore National Laboratories, Livermore,
CA
J. Heckel, Spectro Analytical Instruments, Kleve, Germany
D. Wissmann, Spectro Analytical Instruments, Kleve, Germany
M. van Driessche, Texaco Technology, Ghent, Belgium |
This workshop will discuss features of XRF analysis that are
specific to the polarized technique. More
specifically, it will look at the practical problems of preparing
samples of liquids and powders for
analysis by polarized XRF spectrometry. With an operating
spectrometer, it will examine the procedures
for the analysis of low levels of sulfur in gasoline and for high
precision analysis of samples in
fused glass beads. The use of the Compton method for matrix
corrections will be discussed, and also
the Turboquant method of semiquantitative analysis. This workshop
also seeks contributions from
other participants.
