Information for WAND² Users

Shipping Addresses for Samples

Please visit the ORNL User Facilities Sample Handling and Shipping page.


WAND² instrument control

WAND² is controlled through Control System Studio (CSS). Please refer to the manual WAND² control.

For remote user experiments, please visit the User Guide to Remote Experiments webpage.


Access to HB-2C Data

Data is accessed and reduced remotely on the SNS analysis cluster using Mantidworkbench. A good tool to obtain an overview of your measured files is through ONCat.

The data reduction process has changed in 2021. Please refer to the following manuals for data reduction:

Data from the old WAND can be found and downloaded through ONCat too and may be accessed and reduced using the HFIR Graffiti software. 

Additional Software Downloads:

  • WinSCP is a free SFTP client. Once you reduced the data on the SNS analysis cluster you can use a SFTP client to transfer the reduced data to your local computer.
  • FullProf and GSAS are Rietveld refinement packages for determination of nuclear and magnetic structures.
  • SaraH (download file) – contains the user friendly magnetic structure analysis programs SARAh-Representational Analysis and SARAh-Refine. SARAh uses representational analysis to calculate 'symmetry allowed magnetic structures' . The front-end SARAh-Refine facilitates analysis of magnetic diffraction data in terms of these results with GSAS and FullProf. When used with GSAS, SARAh allows reverse Monte Carlo/ Simulated Annealing refinement of the moment orientations. When used with FullProf, automatic creation and editing of the magnetic phase can be controlled by the user.
  • Graffiti – For data reduction from the old WAND. This program allows the user to browse through the scans in the experiment. It also allows combining data sets, angle calculations, spurion checks, etc. Data download through Graffiti doesn't work anymore. Use ONCat.
  • DAVE - Singe Crystal data from the old WAND is displayed using MSLICE in the DAVE Software package; make sure to enter the correct WAND Offset angle (2θ) and wavelength (1.488Å).  Spice/Graffiti is used to create a .wand file which can be read with MSLICE.

User Publications

Intent to Publish

As a condition for performing nonproprietary research, the US Department of Energy requires users to publish results from their research. Authorship of publications based on research from these facilities should reflect the normal considerations of recognizing collaborations. It is also important to take into account the considerable efforts of the instrument scientists in their role of designing, constructing, and/or operating the instrument and related facilities. Results are typically published in peer-reviewed journals, proceedings, or presentations at technical conferences. Proprietary users are not required to publish.

Credit Line

The HB-2C Wide-Angle Neutron Diffractometer should be acknowledged with this required statement:

[Part of the] Research conducted at ORNL's High Flux Isotope Reactor was sponsored by the Scientific User Facilities Division, Office of Basic Energy Sciences, US Department of Energy.
