How to Submit a Proposal

1. Select an Instrument

View the High Flux Isotope Reactor (HFIR) and Spallation Neutron Source (SNS) Neutron Science Instruments to determine which is best suited for your research.

2. Contact the Instrument Scientist

Once you select an instrument, contact the appropriate instrument scientist to ensure your research is feasible and receive answers to your initial questions. The instrument scientists are listed on each instrument page.

  • Instrument scientists can help
  • Determine if the desired instrument and facility are the best fit for your research.
  • Estimate the amount of facility time needed and justify the requested amount.
  • Determine the proposal typebest suited for your proposed research.
  • Provide constructive comments on your Statement of Research

3. Choose a Proposal Type

Proposal types will vary depending on research and experiment details. The appropriate proposal type for your research can be determined here.

4. Identify Additional Resources

Sample Environment

The Sample Environment group provides a variety of resources for experiments at HFIR and SNS in the areas of soft matter, magnetism, low and high temperatures, engineering materials, and high pressure.

Center for Nanophase and Materials Sciences Characterization

The Neutron Sciences User Facilities, in partnership with the Center for Nanophase Materials Science (CNMS), allow users to request CNMS characterization time within a neutron proposal if the main part of the proposed work will be carried out at HFIR and/or SNS.

To request characterization time at CNMS, include the two-page CNMS Appendix in your proposal’s Statement of Research section in the Integrated Proposal Tracking System (IPTS). The CNMS Appendix can be downloaded here.

If the proposal’s primary purpose is to obtain access to the CNMS facility for synthesis, submit a proposal directly CNMS .

High Performance Computing Resources

Limited access to High Performance Computing (HPC) resources and some support for modeling and data analysis, is provided for work related to data collected at HFIR and SNS.

You must indicate in your proposal if computational support for HPC Resources for modeling and data analysis is needed. Visit Data Management for additional information.

User Laboratories

Laboratories are available at HFIR and SNS to provide a convenient and safe location for experiment preparation and post-experiment sample analysis.

Access to these laboratories is requested during the confirmation process for approved proposals.

6. Create a Proposal

All Neutron Science proposals are created and submitted in the Integrated Proposal Tracking System (IPTS). When creating a new proposal, users are guided through the proposal submission process and prompted to supply the necessary experiment information. Please review the required content for proposals on IPTS Checklist page, before beginning the submission process.

Statement of Research

The Statement of Research is an essential part of the proposal submission process. This two-page document should describe the purpose, importance, and goal of the research to be conducted at HFIR or SNS. Please review Writing Tips for help preparing your Statement of Research.

The template for the Statement of Research can be downloaded here.

7. Proposal Review

All proposals are reviewed and rated for feasibility, safety, and the potential for high-impact science. If a proposal is submitted during a periodic proposal call, the principle investigator (PI) for each submitted proposal can expect to receive notification of review results within eight weeks of the proposal call closing date. The PI will be informed whether their proposal was accepted or rejected for beam time with comments from the review committee. Review the Proposal Rating descriptions below to understand why proposals are or are not selected for beam time.


General User Program Proposal Ratings

Rating Score Description
Extraordinary 5 The proposal involves cutting-edge research of great scientific importance. Proposed research will significantly advance knowledge in a specific field or scientific discipline. The neutron scattering capabilities of HFIR and/or SNS are essential to the success of the proposed work. This proposal must be supported with the highest priority.
Excellent 4 The proposed research is of high quality and has potential for making an important contribution to a specific field or scientific discipline. The work is innovative and is likely to be published in a leading scientific journal. The use of HFIR and/or SNS is highly desirable for the success of the proposed work. It is strongly recommended that this proposal should be supported.
Good 3 The proposed research is inventive and likely to produce publishable results. Impact on a specific field or scientific discipline is likely. The proposed work will greatly benefit from access to HFIR and/or SNS. This proposal should be supported if sufficient resources are available.
Fair 2 The proposed research is interesting, but may not significantly impact a specific field or scientific discipline. Publication may or may not result from this research. Neutron scattering capability is required, but the proposed work could be performed at other facilities. This proposal should not be supported if the required resources are limited.
Poor 1 The proposed research is not well-planned or is not feasible. Results would not make important contributions to fundamental or applied understanding, and work is not likely to result in publication. This proposal should not be supported.
