1.2 Types of Research and Proposals Available for 2025A Beamtime and Online Submission Deadline for 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 Graduate Student Proposal or Long-Term Graduate Student Proposal are your only choice; as a project team member, you can participate in any research project.

[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 A terms only))

If you wish to apply for a one-year proposal, which (a) is applicable only for Non-proprietary Priority Proposals, (b) may allow you to use beamtime in two consecutive research terms (starting in A terms and ending in B terms), and (c) is applicable only in A terms (no call for B 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 shifts for BL41XU and BL45XU, 1 shift for BL26B1, and 1.5 shifts (or 0.25 shifts for Automatic Data Collection without a visit) for BL32XU. Similarly, the minimum allocatable machine-time is 3 shifts for CryoTEM. 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)

List the project leader’s publication (maximum 3) associated with the proposed research (Place an asterisk next to the publications based on research at the SPring-8.) and describe each publication briefly. In addition, register the project leader’s ORCID iD at MyPage, Account Information, if available. (ORCID iD will be used to understand the project leader’s past research activities which is not directly related to the proposed research.)

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.
• – Helium Supply (both liquid and gas)
  Please note that there is a possibility that JASRI cannot provide stable supply of Helium (both liquid and gas) due to the recent situation regarding global helium supply.
