1. 2021B User Operation

1.1 Beamtime Available to Users: 270 shifts (tentative)

270 beamtime shifts will be available for 2021B (from September 2021 to February 2022) .

1.2 Types of Research and Proposals Available for 2021B Beamtime and Online Submission Deadline for Online Proposals (Japan Time)

[Types of Research]

There are two types of research available at SPring-8: proprietary and 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 make their research results available to the public through refereed journals or equivalent. For proprietary research, the research proposals are reviewed only from the viewpoint of feasibility, safety, sociality, and ethics. In this type of research, users are charged a beamtime fee of 480,000 yen/shift based on cost recovery for SPring-8 beamline operation. In return, users are not required to make their research results publicly available.

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 budding researchers support proposal is your only choice; as a project team member, you can participate in any research project.

    • G-mode:4/58-filling + 53 bunches
    • H-mode: 406 × 11/29−bunches + 1 bunch

    Please note that there may be a possibility that the operation in above Bunch Mode cannot be provided depending on the Accelerator Status.

    * The filling modes of F- and G-modes are operated only in research term B (e.g. 2021B, 2022B). In research term A (e.g. 2022A, 2023A), the D-mode (1/7-filling + 5 bunches) and the E-mode (2/29-filling + 26 bunches) will be operated instead of the F- and G-modes. For details, click here.

    If you have a preference for a particular operating mode, choose from the pull-down menu on the Basic Information page of the online application form, and explain the difference in efficiency between your first- and other modes in the box provided for “Others.”

    1.5 Complementary Use with SACLA, J-PARC MLF or HPCI including the K computer / the supercomputer Fugaku

    To encourage research that is expected to produce excellent results more effectively through complementary use with J-PARC MLF (neutron facility) or HPCI including the K computer / the supercomputer Fugaku (public computational resource of High Performance Computing Infrastructure including the K computer / the supercomputer Fugaku) rather than when SPring-8 is used alone, we have been inviting SPring-8 proposals for such complementary use with either or both facilities since 2014A. SACLA has been added to those facilities for complementary use from 2017A. Available types of proposals and beamlines are as follows:

    1. [Available Types of Proposals]
      • General Proposals (non-proprietary only)
      • Budding Researchers Support Proposals
    2. [Beamlines Available to the Program]

    [Important Notes]

    a. Project Leader

    A project leader is the person who will have overall responsibility throughout the experiment at SPring-8. The project leader and the person who is responsible for the research may not be the same person. Likewise, the project leader need not be the first author for SPring-8-related publications.

    b. Application Type (New/One-Year (accepted for B terms only))

    If you wish to apply for a one-year proposal, which (a) is applicable only for non-proprietary General Proposals with use of certain limited BLs and Budding Researchers Support Proposals, (b) may allow you to use beamtime in two consecutive research terms (starting at B terms and ending at A terms), and (c) is applicable only in B terms (no call for A terms), choose One-Year as Application Type.

    c. Use of Multiple Beamlines

    Applicants wishing to use more than one beamline must submit a separate application for each beamline. Submitting multiple applications is not detrimental to applicants if it is deemed appropriate to use more than one beamline. In such a case, applicants may use the same wording in the abstract page of the applications.

    d. Number of Shifts Required (8 h/shift)

    Generally, beamtime is allocated in increments of 3 shifts, however, the minimum allocatable beamtime is 0.25 shift for BL41XU and BL45XU, 1 shift for BL26B1/B2, and 1.5 shifts (or 0.25 shifts for Automatic Data Collection without visit) for BL32XU. Similarly, the minimum allocatable beamtime is 3 shifts for EM01CT/EM02CT. If you need assistance in calculating how many shifts are necessary for your research, please contact the Beamline Scientist.

    e. List of SPring-8 Publications (Repeat Users Only)

    Please be sure to provide the list of publications with brief descriptions in chronological order with the most recent first. List as many as space permits.

    f. High Pressure Gas Cylinder

    If you wish to bring in a high-pressure gas cylinder, please make sure to provide all required information in the online application:
    [Known Safety Hazards & Measures to Be Taken]
    “Does your proposed research involve any of the following?” > Check the box for “High pressure gas cylinder.” Then, fill out the “Details of samples” table properly. Please be advised that if you attempt to bring in a high-pressure gas cylinder without providing the required information in the application, there may be restrictions on the cylinder to be brought into the site during the administrative procedures required by the High Pressure Gas Safety Act.

    g. Mode Operation

    2.3 Radiation Worker Registration

    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. To complete your registration, you must submit a “Radiation Worker Registration Form (Form 5-1)” by post at least 10 days before your visit. Once registered, submission of this form is not required for return visits within the same fiscal year (from April 1 to March 31 of the following year). For details, click here.

    2.4 Others

    • – Safety Precaution
      For your safety, do not work alone. Please include the name of your project team members in the online proposal application and make sure to work in a group of two or more.
    • – Cancellation of Beamtime
      Please be advised that your scheduled beamtime may be cancelled in case of emergencies such as equipment failure, natural disaster, and pandemic. In such cases, users cannot claim compensation for the lost beamtime.
    • – 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. JASRI shall take due account of all relevant circumstances in determining the degree of user liability.
