Use Neutrons in Your Research

Use Neutrons in Your Research

Beam time on two of the world’s most advanced neutron scattering research facilities—the Spallation Neutron Source (SNS) and the High Flux Isotope Reactor (HFIR)—is granted through Oak Ridge National Laboratory’s general user program, which is open to all. In addition, opportunities are available for extended collaboration through programs such as internships and postdoctoral programs.

The instruments at HFIR and SNS are available free of charge with the understanding that researchers publish their results, making them available to the scientific community. The facilities also are available for fee-based proprietary research.

Neutron Sciences Call for Proposals Due September 18, 2018

The Fall proposal call will close at 11:59 a.m. September 18, 2018. This call is for experiments anticipated to run at SNS and HFIR from January to June of 2019.

If you are considering submitting a proposal for 2019-A please make contact with one of our instrument scientists. Detailed descriptions of the instruments and contact information for our instrument scientists can be found on our instrument support pages. 

Check back to this page for updates.

Before submitting a proposal for a specific instrument, please contact the appropriate instrument scientist to make sure your research is feasible for that instrument. Information about the instruments available during each call is available on the instrument pages.

Access to CNMS Characterization Facilities

The Neutron Sciences User Facilities (HFIR/SNS) are partnering with the Center for Nanophase Materials Sciences (CNMS) characterization facilities to allow users to request CNMS characterization time within a neutron user proposal, provided that the main part of the proposed work would be carried out at HFIR and/or SNS. To request characterization time at CNMS, attach the 2-page CNMS appendix with your proposal submission in IPTS. The CNMS request will be reviewed concurrently with the neutron proposal review. HFIR/SNS access for any proposal will still be based entirely on the standard peer-review process. A HFIR/SNS user whose CNMS characterization request is approved in the spring 2018 proposal call will schedule that time between August 2018-July 31, 2019 Note that if the primary thrust of the proposal is to obtain access to the CNMS facility for synthesis, prospective users must submit a proposal directly to CNMS.


ORNL Guest Portal

The ORNL Guest Portal gives you access to all the resources you need as a new or returning user, such as the proposal system, data access and analysis systems, sample handling information, and visitor information.

User Responsibilities

Safety: Safe operations are integral to the ORNL mission. A user must agree to adhere to all relevant safety requirements and to complete all user training deemed necessary by a given facility.

User Agreements: The US Department of Energy requires that its ORNL operating contractor—UT-Battelle (UTB)—and the institution of each user who accesses its User Facilities sign, in advance, a standard agreement dealing with such topics as intellectual property, liability, site access, safety, and publications. The User Agreement is not project-specific, and it applies to virtually all of an institution’s approved proposals at ORNL’s designated User Facilities. If an applicable agreement does not already exist, the user or institution will receive an agreement and instructions from the ORNL Sponsored Research Office.

The NScD User Office will initiate preparation of these agreements for approved proposals, if the agreements do not already exist.


Acknowledgment Statement

All publications based on work done in whole, or in part, at the Spallation Neutron Source or the High Flux Isotope Reactor at Oak Ridge National Laboratory should acknowledge 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.

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


Please submit bibliographic information for your publications to the PuSH (Publications of SNS and HFIR) database.
