Call for SPring-8 Research Proposals – Overview –

If you are interested in using SPring-8, please read the following information carefully before applying.

1. Research Term and Beamlines Available to Users

1.1 Research Term

SPring-8 operates for 2 half-year research terms (A term and B term) each year. A term, the first half of a fiscal year, typically spans from April to August (incl. summer maintenance period); and B term, the second half, is usually from September to March (incl. winter maintenance period).

e.g. A Term 202X from April 1 to August 31, 202X
B Term 202X from September 1, 202X to March 31, 202X

At the beamlines with sixannual calls, however, A and B terms are further divided into three periods.
The beamtime schedule for individual proposals is subject to the results of the coordination of all proposals and may not be as requested.

1.2 Beamlines Available to Users

All 26 SPring-8 public beamlines, CryoTEMs and 11 RIKEN beamlines are available to users. Click here for the current call for proposals for the list of beamlines available to users by type of proposal.

2. Types of Research

There are two types of research available at SPring-8: proprietary and non-proprietary research.

Proprietary Research:

Users have no obligation to publish their research results. In return, proprietary users are required to pay the fee for the beamtime used (See 7.1 Beamtime Fee). Submitted proposals are reviewed only from the viewpoint of technical feasibility, safety of experiment, sociality and ethicality.

Non-Proprietary Research:

Users are exempt from paying the beamtime fee if their research is non-proprietary. For research to be considered non-proprietary, users are required to publish their results with proper acknowledgement and register the published works with the SPring-8 Publications Database within three years from the end of the research term.

3. Types of Proposals

We offer a variety of types of proposals each with distinctive characteristics to suit your research needs as shown in the table 1 below.

Type of ProposalDescriptionsFrequency for call
General ProposalFor general research using synchrotron radiation, with obligation to publish results. Twice/six times a year
Graduate Student ProposalIntended for doctoral students (at the time of experiment) with an exploratory and original research proposal or research theme. Twice/six times a year
Long-Term Graduate Student ProposalProposals that provide an opportunity to secure stable and planned beamtime for doctoral students by making the proposal valid for one to three years during their doctoral program. Submitted proposals need to go through a two-stage review process of application screening and interview. Proposals are accepted for research term B.Once a year
Long-Term ProposalIntended for the proposals that are expected to produce outstanding results through the long-term and well-planned use of SPring-8. The review process consists of two steps: document screening and interview. Once approved, proposals are valid for two years.Once a year (only in the B Term)
Non-Proprietary Priority ProposalIntended for the proposals subject to pay the program fee to prioritize using the beamtime. The users also have obligation to publish their research results. Under the program, the proposals will be granted an exemption from scientific review; only the safety and technical feasibility of the experiment, and ethics (e.g., exclusively for peaceful purposes) are considered. One-year proposals are accepted for research term A.twice/six times a year
Once a year for One-year Proposal
Urgent ProposalDesigned for users with an urgent and critical need to carry out non-proprietary experiments of great public significance.as needed
Proprietary ProposalFor general research using synchrotron radiation, with no obligation to publish results and a simplified review process. A beamtime fee will be charged.Twice/six times a year
SPring-8 Measurement ServiceJASRI staff will perform measurements on behalf of users, and users simply send their samples to SPring-8.as needed
Proprietary Time-Designated Proposal (Beamtime use by shift-based or hour-based)The proposal can be applied at any time, and will be examined immediately after application submitted. The hour-based use proposal program, provides users in the early stages of their research with a convenient opportunity to use SPring-8 to confirm the usefulness or to examine measurement conditions. It can also be used to obtain additional data after the experiment.as needed

If you are considering submitting an urgent proposal, a time-designated proposal or a measurement service proposal, please contact the Beamline Scientist of the beamline of interest in advance for the availability of beamtime.

4. Project Leader Eligibility

[All types of proposals except for Graduate Student Proposal]
Eligible individuals are those who can complete radiation worker registration before using synchrotron radiation at SPring-8 (not necessary for Measurement Service and PX-BL Automatic Data Collection) and be responsible for experiments carried out at SPring-8 as a leader. Please note that students are not eligible.

[Graduate Student Proposal]
If you are a doctoral student (at the time of experiment) and wish to apply for beamtime (submit a proposal as a project leader), the Graduate Student proposal is your only choice (as a project team member, you can participate in any research projects). You may be a master’s or doctoral student at the time of proposal submission; but you must maintain your doctoral student status at the time of experiment. Otherwise, your proposal will be switched to a general proposal.

5. Beamtime Available to Users

 Maximum percentages of allocable beamtime (varies by type of proposals) are summarized in the following Table 2.

from 2023A Term

until 2022B Term

9. Important Notes

  1. Radiation Worker Registration
    The Japanese Law (Ordinance on Prevention of Ionizing Radiation Hazards) requires SPring-8 users, excluding non-visiting users using Measurement Service/PX-BL Automatic Data Collection, to be registered as SPring-8 radiation workers. For details, click here.
  2. Safety Precaution
    For your safety, do not work alone. Please include your project team member in the online proposal application and make sure to work in a group of two or more.
  3. Reduction/Cancellation of Beamtime
    Please be advised that your scheduled beamtime may be reduced or cancelled in emergencies such as equipment failure and natural disaster. In such cases, users cannot claim compensation for the lost beamtime.
  4. General Insurance and Compensation
    Users shall take out appropriate personal injury and liability insurance before conducting experiments. If their project teams include students, they shall make sure that all the students take out appropriate personal injury and liability insurance. If users damage SPring-8 facilities, equipment or persons, either willfully or through gross negligence, JASRI may require them to meet all or part of the cost of repairs.
