How to apply



Research Institute for Synchrotron Radiation Science (HiSOR) calls for collaborative research proposals using synchrotron radiation in the vacuum ultraviolet and soft x-ray regions.

1. Proposal category and deadlines for submission

(1) Proposal category G (General proposal)

Proposals in category G are accepted twice a year and assigned beamtime for the Period A (beamtime from April 1, 2024 to March 31, 2025) and Period B (beamtime from November 1, 2024 to October 31, 2025). The submission deadlines are as follows:
Period A: January 8, 2024
Period B: June 30, 2024

The beamtime schedule will be planned, taking into account your preferences. As most of the allocatable beamtime will be filled by category G proposals, we advise to submit proposals to this category. Due to frequent overbooking of the undulator beamlines (BL-1, 9A, 9B), proposals will be ranked by academic significance and justification of the requirement on these beamlines, and the number of granted shifts may be reduced. If a proposal was not assigned beamtime or the allocated beamtime was insufficient to complete the experiment, resubmission of the proposal to the next period is possible.

*From the Period B in 2022, the beamtime allocation period according to this proposal has been expanded from half year to one year. However, as usual, we will not change the open call for proposals twice a year as shown above.

(2) Proposal category U (Urgent proposal)

After the deadline for the category G, we may accept a limited number of urgent proposals, which should have significant academic importance and urgency during the periods. The allocation of the category U beamtime is not as flexible as category G. For undulator beamlines, detailed descriptions are needed why the proposal should be done in the category U (please clearly describe significance, justification, and urgency). If the proposal was not assigned beamtime, resubmission of the proposal for the following period in the category G is possible.

2. Submission

Before submitting proposals, we would like to ask you to contact the in-house staff in charge of the beamline which you are interested in. If you already used these beamlines, please directly contact the in-house staffs before proposal submission. If you are new to HiSOR, please send an e-mail to the HiSOR user office (hisor(AT)*Please replace (AT) with @)), and ask for the in-house staff of the beamlines you are interested in.
You can download proposal forms from
Please select an appropriate form according to the period you would like to have your beamtime.
As we need original forms with signatures, we would like to as you to send the final proposal application by mail. To facilitate official procedures (especially for the category U), however, please send the electronic file by e-mail in advance, and mail the original later.

*From the Period B in 2022, we add in a part of “publications and status of the HiSOR activity reports related to your proposal numbers accepted within 3 years”. If you are applicable, please be sure to fill in this part.
