* Notes on the proposal application by graduate students

• Graduate students intending to make an application as a Principal Investigator are required to contact the instrument scientists before submitting the proposal.
• Enter “Graduate Student” in the field of the applicant’s job title.
• Indication of AS and ES
  • The applicant's academic supervisor must be registered as a Collaborator. In the field of job title, add “AS” after his/her job title.
  • An academic staff member of the applicant’s university, which includes his/her academic supervisor, and research collaborator (not including graduate students) is required to attend and supervise the experiment (experiment supervisor). The experiment supervisor must be included as a Collaborator. In the field of job title, add “ES” after his/her job title.
       e.g. : Professor, AS   Research staff, ES   Professor, AS, ES
    ※Application without AS and ES will not be accepted.
• If the proposal has been approved, the academic supervisor is required to submit the specified pledge for implementing the experiment.
  

【Export control for experiments by non-residents of Japan or residents of Japan with strong association to foreign countries】
In principle, experiments implemented by non-residents of Japan or residents of Japan with strong association to foreign countries are subject to export control (research team members, sample, obtained data, etc.). Please note that there is a case where the implementation of the experiment will not be permitted depending on the results of the screening of export control even if the experiment has been approved through proposal selection screening. With regard to applicants who belong to the organizations listed in the Foreign End User List of METI or the nationals of non-NPT countries, eligibility to apply is decided in consultation with MEXT etc.

4. Requirement of onsite participation

• The instrument scientist will not conduct experiment on behalf the PI. It is required that the PI or other research team member(s) come to J-PARC MLF to conduct the experiment including the preparation of the experiment.
• If the PI and the instrument scientist agree by 30 days prior to the scheduled experiment day that there is no prospect of implementing the experiment, the beamtime will be canceled. And if such a member is coming from abroad, be sure that he/she can obtain an appropriate visa.
• Please refer to the websites of Ministry of Foreign Affairs of Japan for information on necessary procedures, conditions for coming to Japan, etc.

5. Instruments available for General Use Proposal

Please contact the instrument scientist for the specification of the instrument.

• Proposals using BL08 (SuperHRPD) and BL16 (SOFIA) need to consult the instrument scientist about the experiment in advance.
  
• In the case of intending to conduct joint research with the instrument scientist(s) of muon beamlines, please consult with them in advance and agree on their roles in the experiment before submitting the application.

6. Choose the review field

Please choose the appropriate category from the list below. The proposal is reviewed by the subcommittee of the category.
List of keywords for each sub-committee.

7. Evaluation criteria

• Submitted proposals are assessed and selected based on the evaluation criteria.
• The scientific value of the proposal and the appropriateness of the necessary beamtime will be taken into consideration when deciding the beamtime.

8. Please Note

1. Use of samples including nuclear fuel materials/elements is prohibited. Only RI samples permitted by the MLF may be used.
2. Be sure to consult the instrument scientist prior to proposal submission if special sample environment (magnet etc.) is required.
3. If the sub-committee decided that a different beamline is more suitable for the experiment than the beamline you have chosen, the beamline may be changed.
4. Users who intend to bring in electrical equipment whose power output rating is 7.5kW and above/7.5kVA and above or equipment whose current rating is 30A and above must include the detailed equipment specifications in the research plan.
5. KEK beamlines (refer to “Instruments available”) cannot accept undergraduate students as Collaborators. However, they can participate in the research as interns. If a graduate student participates as a Collaborator, write “Graduate Student” in the field of the job title.
6. Experiment is not allowed to be implemented if it is attended only by students (including graduate students).
7. If researchers belonging to a private company want to use a muon instrument, please contact us at the email address indicated at the bottom in advance.
8. J-PARC also welcomes P-type proposals to conduct test experiments in preparation for general use and Project use (S-type use) proposal as well as proposals from the users who have no experience in muon use. For more details, please click here.

9. Indication of keywords

Please list up to 5 keywords that briefly describe the proposal in the Research Plan template.

10. Complementary Use

Please indicate if your proposed research includes, or is likely to include in the future, the complementary use of other major research facilities such as, but not limited to, synchrotron radiation sources (SPring-8, SACLA, PF, etc.), JRR-3, supercomputer(HPCI including Fugaku computer etc.), or other quantum beam facilities.
If the above applies to your proposal, indicate the details in the Research Plan template. This information will be used only to survey current trends in research proposals at the MLF.

11. Charge for use

Proprietary Use Charge is 2,983,000 JPY (tax included)/ day

12. Publication of results (Non-Proprietary Use)

• PI of Non-proprietary use experiment is required to submit an Experimental Report within 60 days after the end of the proposal round (deadline of report is here). The report will be published on the J-PARC Web site.
• Please publish the results of the experiment within 3 years after the completion of the experiment.
• Submission of the Experiment Reports of the past experiments conducted at the MLF and the publication of the results will be taken into account in the future proposal review.
• When publishing the results, it is recommended to consult with the instrument scientists in advance about who should be the co-author. It is also important to take into account the support provided by the instrument scientists and other staffs maintaining and operating the facility when deciding the co-authors. Please also indicate the proposal number and the beamline(s) used for the experiment in the publishment.

13. Disclosure of information

• The information below on the approved and completed experiments (Non-proprietary use and Proprietary use) will be published on the website.

14. Additional call for proposals

There may be an additional call for proposals in the case where the total of the applied beamtime in this call for proposal is less than the available beamtime. In that case, information will be released on the website etc.

15. Notification of review result

The review results will be sent to the applicants’ email addresses registered in the Proposal Submission System. The provisional notification will be sent around August 2022, and the official notification is planned to be sent after all the review process has been completed, which will be in September 2022.
