Available software

There are a number of software packages available to NCNR users.  Some must be used locally at the NCNR and others may be downloaded and used at your home institution.  This page is a list of the available programs organized by topic.  Those programs that can be downloaded are indicated with a D in parentheses (D) but most of these programs can be run locally on JAZZ.  The platforms supported for the downloadable programs are indicated within the web pages.

CRYSTALLOGRAPHY GSAS (D) CMPR (D) Display, index and fit diffraction data Support for CMPR: Brian Toby EXPGUI (D) Reduction and analysis of data for x-ray and neutron diffraction measurements: BT-1 Support for EXPGUI: Brian Toby other crystallography resources Consult the web pages above for support of the crystallography programs

INELASTIC NEUTRON SCATTERING DAVE (D) For reduction, visualization and analysis of data from DCS, FCS, HFBS, SPINS, FANS (BT-4), BT2, BT7 and BT9 Support for DAVE: Richard Azuah XTREAT, TANQENS For reduction and analysis of data from FCS Support for XTREAT and TANQENS: Taner Yildirim and Craig Brown SPURION For calculation of spurious peaks in triple-axis experiments Support for spurion program: Tanya Riseman FIT (D) For fitting generic columnar-formatted datasets. Support for FIT: Ross Erwin

REFLECTIVITY REFLRED, REFLFIT, REFLPOL (D) Reduction, visualization and analysis of data from the NG-1 and NG-7 reflectometers Support for the reflectivity programs: Paul Kienzle

SANS IGOR* programs (D) For reduction, visualization and analysis of data from USANS, NG-1 SANS, NG-3 and NG-7 SANS Support for SANS software: Jeff Krzywon

On-line calculators**

In addition to the resources above, there are a number of Java applets accessible on-line for experimental planning and simulation.  Links to these programs are listed below.
NCNR tools on the web (reflectivity, scattering length density, self-shielding, etc.)
Neutron attenuation and activation (BT-1)
X-ray absorption calculator


DVA Team

The DVA team is responsible for meeting the visualization and analysis software needs of the NCNR scientific staff and user community.  There are a number of software packages listed above that are relatively mature and some that are in the development phase.  The two major efforts currently in the development phase are the DAVE project and reflectivity software development.
