Here is a special item for small-angle scatterers. who will be attending the 1998 ACA Annual Meeting Announcement - ACA Workshop on Data handling for Small-Angle Scattering Washington, DC, 18 July 1998 As the Small-Angle Scattering Community expands the need for increased attention to issues relating to the handling of SAS data is becoming apparent. The IUCr Commission on Small-Angle Scatering and the ACA Small-Angle Scattering Special Interest Group have therefore decided to convene a workshop to examine the current state of the art in this area. The panel will consist of John Barnes (NIST, USA), Malcolm Capel (NSLS, USA), Jan Skov Perdersen (Risoe, Denmark), and Dmitri Svergun (EMBL, Germany). The Topics discussed will include handling the raw data as it comes out of the experiment, reducing the data to commonly accepted forms, and analyzing it using both structural models and indirect transform methods. A tentative syllabus for the workshop is given below: A. Data acquisition issues A.1 Instrumentation issues A.2 Formats for Acquiring data A.3 Capturing Experimental Parameters A.4 Calibration data B. Data Reduction issues B.1 Backgrounds B.2 Unscattered primary beam B.3 Sample cells B.4 Applying Corrections B.5 Calibration and scaling B.5.a Q Scale calibration B.5.b Absolute Intensity calibration B.6 Error propagation B.7 Portable data formats for interchange and visualization (e.g. NEXUS) B.7.a Self-description B.7.b Completeness B.7.c Accessibility C. Data Interpretation Issues C.1 Data Input C.2 Simulation C.3 Fitting C.4 Indirect Transform Methods C.5 Resolution Effects C.6 Estimating errors in the parameters D. Software resources D.1 Data Visualization tools D.2 Modelling and simulation tools Preregistration is required for those who wish to participate. Please see the WWW page for the meeting at http://www.hwi.buffalo.edu/ACA/ACA-Annual/Washington/Washington.html for more information about all aspects of the meeting. The "Schedule of Sessions" link on that page will eventually get you to more information about the Workshop. Dr. John D.
