Call for Urgent Proposals

The urgent proposal program is designed for users with an urgent and critical need to carry out non-proprietary experiments of great public significance. Urgent proposals can be submitted at any time, and submitted proposals are reviewed on a rolling basis.

1.Beamlines and Beamtime Available to Users

All 26 public beamlines and 11 RIKEN beamlines are available. If you would like to use the RIKEN beamlines available for public use, please contact the SPring-8 Users Office of JASRI. If you don’t have previous experience using the beamline you would like to use, please make sure to consult the Beamline Scientist before submitting a proposal. Since the beamtime for urgent proposals is arranged after the beamtime for other types of proposals is fixed, please check the schedule with the Beamline Scientist beforehand.

2.Application Method

Please submit your proposal application online from the User Information Website (UI site). Before starting the application process, please first carefully read the “Call for SPring-8 Research Proposals -Overview-.

3.Submission Deadline

We accept applications on a rolling basis (no specific submission deadline). Please allow at least three weeks for processing (from the date of application until you can carry out your experiment).

4.Review Criteria

Submitted proposals are reviewed and selected by the SPring-8 Proposal Review Committee (SPring-8 PRC). In addition to scientific and technical value, the degree of expectation to produce results, necessity of SPring-8 as a research tool, technical feasibility, safety of the experiment, and ethics, which are the criteria for general proposals, urgency and significance of the proposals are also reviewed at the SPring-8 PRC.

5.Notification of Review Results

Applicants will be notified of the review results by phone or via email about two weeks after the proposal submission. An official written notification will be sent at a later date.

6.Report Submission

Please submit an Experiment Summary Report online within 60 days after the experiment. Submitted reports are made publicly available online two weeks after the report submission deadline for the last experiment of the term (60 days after the end of each half-year research term + two weeks). For details, please click here.

7.Publication of Research Results

Publish your research in a refereed journal or equivalent (refereed proceedings, Doctoral thesis, etc.) and register the publications with the Publications Database within three years after the end of the research term. If the proposed research did not result in a publication, please publish your research results in a SPring-8/SACLA Research Report or a technical journal.
