2. Eligibility Requirements

The eligibility criteria are the same for both General Proposals and Advanced Research and Development Proposals:

• Applicants (Project leaders) must be affiliated with a company, university, or research institution, either in Japan or abroad. (However, students may only participate as collaborator researchers, not as project leaders.)
• Applicants (Project leaders) must secure at least two experimenters. (Experiments conducted by a single individual are not permitted.)

3. Types of Proposals and Available Beamlines

Types of Research Proposals

NanoTerasu only calls for Non-Proprietary Proposals in 2026A term, there is no call for Proprietary Proposals. For research to be considered non-proprietary, users are required to make their research results available to the public through refereed journals or equivalent. Students (including graduate students) can only participate in experiments as collaborator researchers. The call for the 2026A Research Proposals is shown in Table 2.

<Table 2. Types of Proposals Available for 2026A Beamtime>

For the specifications, status of experimental stations and features, please check the Table 3 List of Public Beamlines, Table 4 List of Beamline Features, and Table 5 The features of Coalition Beamlines.

<Table 3 List of Public Beamlines>

<Table 4 Features of Public Beamlines>

<Table 5 Features of Coalition Beamlines>

For applications to Advanced Research and Development Proposal, please contact the office listed below in advance.
If you are unsure whether the equipment you intend to use falls under General Proposals or Advanced Research and Development Proposals, please also contact the office below.

4. Requirements

(1) Application for Beamtime

Applicants/project leaders are required to submit proposals online from the User Information website (UI site) through the web-based proposal submission system. Log in to the system with your user ID number and password. If you have not obtained your user ID number, please complete user registration first. Please note that only the project leaders can submit proposals. Before starting the application process, project leaders must make sure that all project team members have completed user registration. To avoid losing work in the event of a browser crash or unexpected logout, you are strongly encouraged to first draft your application offline using the MS Word template available from here. Upon successful submission, you will receive a confirmation email attached with a copy of the Agreement (Rules for Users) in PDF format. If you do not receive confirmation within a reasonable time, please login to the proposal system and check if your proposal has been submitted.
For the Advanced Research and Development Proposal, please submit your application using the designated form.

(2) User Registration (Not Required of Repeat Users)
To submit an application online, you must have obtained a user account (user ID number and password) by registering yourself. Please make sure that not only project  leaders/applicants but also all project team members are registered as NanoTerasu users.  If you are not registered as a NanoTerasu user, click here to register.
Note: Registration information is also used for contact. If any of your registration information changes, you must update it from the UI site.

(3) Important Notes

[Number of Shifts Required (8 h/shift)]
Generally, beamtime is allocated in increments of 3 shifts. If you need assistance in calculating how many shifts are necessary for your research, please contact Beamline Scientist from following contact details.

*Please replace # with @ in the e-mail address.

[Project Leader]

A project leader is the person who will have overall responsibility throughout the experiment at NanoTerasu. 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 NanoTerasu-related publications.

[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.

[List of Past Publications (Repeat Users Only)]

List the project leader’s publication (maximum 3) associated with the proposed    research and describe each publication briefly. In addition, register the project leader’s ORCID iD at MyPage, Account Information, if available. 

[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.

5. Fees

Please also refer to the “Fees for Beamline Use for Proposals” webpage summarizing fees for public beamline use and user fees.

(1) Beamtime Fee

 [Non-proprietary Research]

*For research to be considered non-proprietary, users are required to disseminate   their research results through refereed journals within three years from the end of the half-year research term. For details, click here.

(2）User Fee 

Public beamline and Coalition Beamlines users are required to pay the fees to cover the costs of beamline maintenance/operation and consumables actually used (user fees). User fees are composed of a fixed fee charged for wear and tear on the facility and a variable fee charged for liquid Helium.

[Fixed Fee]

[Variable Fee]

A variable fee will be calculated and added in accordance with the amount of liquid helium actually used. Please note that the unit price of liquid helium is subject to change.

6. Others

[Registration of radiation workers, etc.]
At the NanoTerasu beamlines, registration as a Radiation Worker (primarily for hard X-ray BLs) or as a BL User (primarily for soft X-ray BL) is required.
Please follow the procedure according to your usage. For details, please see the “User’s Guide” on the NanoTerasu official website and “For those with an Approved Proposal” on the NanoTerasu User Information website.

When using soft X-ray Beamlines:

*1：Required to take an E-learning System for Radiation Safety Training Session  at NanoTerasu or your affiliated institution, and a special medical checkup for radiation users at your affiliated institution.
*2: Required to take an E-learning System for Radiation Safety Training Session  at NanoTerasu.

When using hard X-ray Beamlines:
The hard X-ray beamlines for the 2026A term are as follows.

*1：Required to take an E-learning System for Radiation Safety Training Session  at NanoTerasu or your affiliated institution, and a special medical checkup for radiation users at your affiliated institution.
*2: Required to take an E-learning System for Radiation Safety Training Session  at NanoTerasu.

1. Safety Precaution 
   For your safety, do not work alone. Please include your project team members in the online proposal application and be sure to work in a group of two or more.
2. 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.
3. 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.
