Information for VERITAS Users

VErsatile Intense Triple-Axis Spectrometer

VERITAS | HB-1A | HFIR

Shipping your samples:

Please visit the ORNL User Facilities Sample Handling and Shipping page for the correct shipping addresses.

Access to VERITAS data:

All data can be accessed through ONCat or the analysis cluster.

Sample Environments:

A list of equipment available at VERITAS can be found in the Sample Environment Equipment Database. The database contains detailed equipment specifications and images, drawings and other related documents.

Planning for your experiment:

Scheduling your experiment:

Once you are notified of an approved proposal, please update your impossible dates in IPTS as soon as possible to ensure that they are accommodated in our instrument schedule.

Note that there may be limited scheduling flexibility for your VERITAS experiments requesting the use of extreme sample environment (e.g. cryostats, cryomagnets, ultra-low temperature inserts) due to our sample environment block scheduling system.

Sample preparation: single crystal pre-alignment

If you need to pre-align your single crystal samples using the neutron alignment station (CG-1B) or the Laue machine at SNS before your VERITAS experiment begins, please email the VERITAS instrument team well in advance so alignment time can be reserved for you on the appropriate instrument. Note that we have a first come, first served scheduling system for CG-1B. Also, please let the VERITAS instrument team know if you are experienced with sample alignments or if you will require significant assistance.

Acknowledgement Statement for 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: Research should be published acknowledging ORNL and the facility, or facilities, with this required statement:

This research [or, A portion of this research] used resources at the High Flux Isotope Reactor [and/or Spallation Neutron Source, as appropriate], a DOE Office of Science User Facility operated by the Oak Ridge National Laboratory. [If applicable: The beam time was allocated to [Instrument] on proposal number IPTS-XXXXX.X.]

In addition, users are asked to credit the instrument(s) used in the body of the paper.

Contribute to Our Publication Records: Please submit publications, theses, patents, etc., via the Publications Portal to help us track instrument publications. Both the credit statement and PuSH link are on the Neutron Sciences Publications website.
