New Developments in Data Analysis at IPNS

The ISAW project has produced software now used to visualize, correct, and transform data for several classes of instruments at IPNS and ISAW software is beginning to be used elsewhere. During the last year improvements have been made which greatly enhance the usefulness of ISAW. Recent advances include 1) a data analysis package for Single Crystal Diffractometers, 2) a data reduction package for small angle scattering, 3) a data reduction package for total powder diffraction, and 4) a newly designed set of viewers which work with basic data arrays and thus do not require the more complex data objects used for the first generation of viewers. The new viewer design allows more general use of the ISAW viewers, but still allows building complex views from basic view components. The NeXus team has included these new viewers into the NXValid program which reads, validates, and displays the contents of NeXus files (See http://www.neutron.anl.gov/nexus/NXvalid.html ). The SCD software provides a method for indexing peaks based on identifying planes of peaks in reciprocal space as well as interactive two and three-dimensional viewers for reciprocal space. I will report on these recent developments and future plans including plans for collaboration with SNS, ISIS, Cal Tech, and LANSCE.
