2. The proposal types and experiment period

For More Information

*A pre-application is required to apply.

**The detailed operation schedule will be determined and announced in consideration of the rising electric prices.

3. Prior consultation necessary for application

【Sample environment and experiment conditions】

Please consult the instrument scientists in advance about the sample environment and experiment conditions. The proposal may not be approved if it is considered that the experiment cannot be implemented because the necessary sample environment/experiment conditions cannot be provided.
Contact information: List of Instruments

• BL08 (SuperHRPD, Super High-Resolution Powder Diffractometer)
• BO16 (SOFIA, Soft Interface Analyzer)

Please be sure to contact the instrument scientists in advance to discuss the experiment details if you apply for beamtime of these 2 beamlines.
Contact information:BL08、BL16

【Proposals using Muon D1, D2, or S1】

• D1 (Muon Spectrometer for Materials and Life Science Experiments)
• D2 (Muon Spectrometer for Basic Science Experiments)
• S1 (ARTEMIS, General purpose µSR spectrometer)

If you apply for beamtime of these 3 beamlines and add a muon section staff member as a collaborator to coordinate with the facility, please consult with the beamline scientists and agree on the role of the facility before submitting the application.
Contact information: Muon D1、Muon D2、Muon S1

【First time and novice users of neutron/muon beamlines】

J-PARC Center is accepting consultations from first time and novice users of neutron/muon beamlines. If you are considering using the neutron/muon beamlines, please contact us through Neutron and Muon Users Poral Site (J-JOIN).

4. Selection of the review field

The submitted proposals are reviewed by each research field. Please choose the appropriate research field when applying.
List of keywords for each research field.

5. Instruments available for this proposal round

Please contact the instrument scientists for the specification of the instrument etc.

6. Points to note for proposal application

• If you cite text or figures from other papers or other sources, please be sure to clearly indicate the source of the citation. If plagiarism is identified in the application during the review process, the application may be withdrawn.
• Please obtain the consent of the person concerned before adding them to your list of collaborators. This also applies when the collaborator is an MLF staff member. Proposals may be rejected if a person is included as a collaborator without his/her consent.
• Use of samples including nuclear fuel materials/elements is prohibited. Only RI samples permitted by the MLF may be used.
• 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.
• 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.
• 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.
• 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..

7. Indication of keywords

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

8. Complementary Use proposals

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.

9. Evaluation process and criteria

• Submitted proposals will be reviewed, through the prescribed review process, from comprehensive and specialized viewpoints based on the evaluation criteria. The beamtime of the proposal will be determined in consideration of the scientific merits of the proposal and adequacy of the necessary beamtime.
  
• If the review panel has judged that there is a more appropriate beamline than the one requested, the beamline may be changed.

10. Conditions for conducting experiments for approved proposals

• In principle, the instrument scientists will not conduct the experiment on behalf of the users. Please ensure that the PI or another team member comes to the MLF to conduct the experiment (including the preparation).
  
• 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. (If such a member is coming from abroad and a visa is necessary, 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.
  
• Experiment is not allowed to be implemented if it is attended only by students (including graduate students).
  
• 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 proposal application has been received or the experiment has been approved through proposal selection screening.

11. Charge for use for Proprietary Use Proposals

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 experiment period (deadline of report is here). The report will be published on the J-PARC website.
• 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. (Sample Acknowledgements)

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 2023, and the official notification is planned to be sent after all the review process has been completed, which will be in September 2023.
