User software for the next generation
  New generations of neutron scattering sources and instrumentation are providing challenges in data handling for user software. Time-of-Flight instruments used at pulsed sources typically produce hundreds or thousands of channels of data for each detector segment. New instruments are being designed with thousands to hundreds of thousands of detector segments. High intensity neutron sources make possible parametric studies and texture studies which further increase data handling requirements. The Integrated Spectral Analysis Workbench (ISAW) software developed at Argonne handles large numbers of spectra simultaneously while providing operations to reduce, sort, combine and export the data. It includes viewers to inspect the data in detail in real time. ISAW uses existing software components and packages where feasible and takes advantage of the excellent support for user interface design and network communication in Java. The included scripting language simplifies repetitive operations for analyzing many files related to a given experiment. Recent additions to ISAW include a contour view, a time-slice table view, routines for finding and fitting peaks in data, and support for data from other facilities using the NeXus format. In this paper, I give an overview of features and planned improvements of ISAW. Details of some of the improvements are covered in other presentations at this conference.
