1. Program Objective & Partner Facilities

To promote scientific research expected to yield superior outcomes through cross-facility collaboration rather than using SPring-8 in isolation, JASRI invites Complementary Use Proposals combining SPring-8 with one or more major national research infrastructures:

• SACLA: X-ray Free Electron Laser Facility (JASRI)
• J-PARC MLF: Materials and Life Science Experimental Facility – Neutron Facility (CROSS)
• HPCI (including Fugaku): High Performance Computing Infrastructure incorporating the supercomputer Fugaku (RIST)

2. Eligible Application Scenarios & Proposal Types

A proposal is eligible for the Complementary Use Program under any of the following three scenarios:

• Scenario A (Post-Approval Application): Proposals approved or already conducted at SACLA, J-PARC MLF, or HPCI (Fugaku), for which a complementary SPring-8 proposal is now being submitted.
• Scenario B (Simultaneous Application): Proposals submitted simultaneously to SPring-8 and one or more partner facilities for the same research term.
• Scenario C (Planned Sequential Application): Proposals submitted to SPring-8 with plans to submit a follow-up proposal to SACLA, J-PARC MLF, or HPCI (Fugaku) after completing the SPring-8 experiment.

Eligible SPring-8 Proposal Categories: General Proposals and Graduate Student Proposals.

3. Step-by-Step Online Submission Procedure

• Independent Facility Submissions: Applicants must submit separate proposal applications to each respective organization (JASRI for SACLA, CROSS for J-PARC MLF, and RIST for HPCI/Fugaku).
• Select Proposal Category: Log in to the SPring-8 User Information (UI) Website, create a new application, and select either General Proposal or Graduate Student Proposal.
• Enable Complementary Use Flag: Check the box labeled ‘Complementary Use of SPring-8/SACLA, J-PARC MLF, or HPCI including supercomputer Fugaku’ in the online form.
• Complete Complementary Use Abstract: In the dedicated Complementary Use section, select partner facility names and clearly describe: (a) research objectives, (b) justification for multi-facility access, (c) anticipated synergistic effects, and (d) specific details of approved or simultaneous applications (proposal numbers, titles, PIs, research groups).

4. Independent Peer Review & Result Dissemination

• Independent Evaluation: Proposals are reviewed independently by each organization (JASRI, CROSS, and RIST) according to their respective review criteria. Approval by one facility does not guarantee approval by partner facilities.
• Public Designation: When accepted by JASRI, the proposal will be publicly designated as a ‘SPring-8 Research Proposal in Complementary Use’ regardless of the outcome at partner facilities.
• Industrial Application Subfield: If applying under the Industrial Application subfield, proposals are evaluated with emphasis on industrial technology significance, economic impact, and social value.
