Call for 2017B J-PARC, MLF Long-Term Proposals Application Guidelines

Call for J-PARC MLF 2017A General Use Experimental Proposals (Long Term) has closed.

The Materials and Life Science Experimental Facility (MLF) of J-PARC is pleased to announce a call for General Use Experimental Proposals (Long Term) with beamtime allocations starting in 2017B, hereinafter referred to as Long-Term Proposals.

1. Long-Term Proposals

We are calling for Long-Term Proposals valid for up to 3 years (or 6 proposal rounds)*, which should have a clear long-term strategy for research and development and hold the expectation of yielding outstanding results.

* Each year for a Long-Term Proposal starts in the B term and ends in the following A term.

A Long-Term Proposal is categorized as nonproprietary research. As a condition of performing nonproprietary research, J-PARC MLF requires users to submit their Experiment Report, publish the results of their research, and register their publication on the Result Management System.

2.Application Period

Pre-submission: from Friday 13 January 2017 to 17:00 (JST) Thursday 2 February 2017
Final-submission: from Friday 10 February 2017 to 17:00 (JST) Thursday 30 March 2017

Any proposals without pre-submission will not be accepted as a final proposal.

3. Submission Procedure

Please download pre-submission form and two types of final submission forms from the Web site below. Apply your proposal in a PDF file form by e-mail.

For the final submission, applicants are requested to submit an “Application Form for General Proposal (Long Term) at MLF” and “Application Form for Individual Experiments for Long Term Proposal at MLF” on each beamline that they plan to use.

4.Use of Multiple Instruments and BT Requests

The use of multiple neutron instruments except BL03 and BL20 is allowed in a Long-Term Proposal.*

* Inclusion of muon instruments after 2018 is under consideration.

If using multiple experimental instruments, the applicant is requested to indicate the instruments (not limited to one instrument) that are indispensable to obtaining academic achievements as Main Instruments. A Long-Term Proposal is approved when all the Main Instruments are available for the experiment after proposal review.
Beamtime allocation to Long-Term Proposals is limited to approximately 5% of the total number of MLF operation days for users each year. Therefore, there are several conditions for beamtime requests in Long-Term Proposals. The total beamtime request should not exceed 20 days, and the beamtime request for each Main Instrument should be less than 10 days.
The MLF is expected to operate for 176 days yearly, but it depends on the budget and operational plan for each year. If the MLF operation period could be much more limited than usual, we have to set lower maximum limits for total beamtime and the beamtime for each Main Instrument.

For further information on the MLF user program, such as MLF basic policies, types and categories, proposal submission/review and procedure overviews, please visit the MLF Web site.

5.Period of use and expected beampower

Period of use (expectation): 2017 November~2020 October

Expected beam power (expectation)

2017 Nov. - 2018 Jun.: 300 - 600 kW
2018 Oct. - 2019 Jun.: 500 - 1000 kW
2019 Jun. - : 800~1000 kW

Please estimate your beamtime with 500 kW for the first one year (2017B and 2018A), and 800 kW for the terms after 2018B.

6.Experimental instruments for the Proposal

Instruments for the Long Term Proposals are as follows. The details of the instruments can be obtained here.

Neutron Instruments

Neutron diffractometer
Neutron Inelastic Spectrometers
Neutron Instruments for Nano-Structure
Other Neutron Instruments

*PB: For the Public Beamlines (BL01, BL02, BL11, BL15, BL17, BL18 and BL22), CROSS-Tokai accepts proposals jointly with MLF via the J-PARC Proposal Submission System.

7.Eligibility Criteria

Applicants are expected to be researchers affiliated with universities (domestic or international), public institutions or private companies. Students cannot be applicants.
Researchers affiliated with or wishing to apply from the following entities should contact the J-PARC Center Users Office to determine whether there is any restriction on their applications for beamtime:

8. Important Points Related to Call for Proposals

Pre-submission and Liaison

Applicants are requested to provide the information on their proposal title, abstract and collaborators list in the pre-submission application form. J-PARC/MLF recommends that they involve experts on pulsed neutron experiments and the utilized Main Instruments. In the Liaison column of the proposal, please give the name of a MLF staff member with his/her agreement who will serve the function of sharing information from the facility and the utilized instruments and arranging sample environment apparatus and beamtime. We will call that MLF member the Liaison.

We will accept the pre-submission even if the applicant cannot appoint a Liaison.

After the pre-submission is accepted, the MLF may give advice about the appointment of a Liaison.

Final Submission

Applicants are requested to submit a Final Proposal after careful deliberation by the collaborators including the Liaison.

Restriction of Duplicate Proposals

A principal applicant can submit one Long-Term Proposal in its valid term. An applicant with a Long-Term Proposal under review can submit a General Proposal (Short Term) for the same experiment. If the Long-Term Proposal is approved, the applicant should merge the projects. (The General Proposal (Short Term) should be withdrawn.) If an applicant has an accepted Long-Term Proposal, he/she cannot submit a General Proposal (Short Term) with a similar purpose.

Elements Strategy Initiative & Complementary Use

Applicants will be asked to indicate if their research has affinity with the Elements Strategy Initiative. Similarly, applicants will be asked if their 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 facilities (SPring-8, SACLA, KEK-PF, etc.), the K computer, or other quantum beam facilities. If either of the above applies to your proposal, please indicate by marking the relevant tick box and adding a brief description as requested.


The Review Committee may hold hearings after documentation screening. The assessment of proposals will take into account whether Experiment Reports for previous beamtime allocations had been submitted as required and whether publications had been properly registered.

9. Execution of Accepted Long-Term Proposals

Yearly procedure

The principal investigator is requested to submit a research plan every year as well as renewal application(s) for each experiment on each beamline, which will show the current status of the research and the details of each experiment for the following year.

Safety review

Safety aspects of the experimental procedure, test sample(s) and user-brought instrument(s) are reviewed at the time of proposal submission and at each renewal juncture.

Presenting outcomes

The principal investigator is requested to present the outcome of the research at the Quantum Beam Science Festa (in a poster presentation) after conducting research for one year.

Interim evaluation

The Long-Term Project must be subjected to an Interim Evaluation in the second year. The principal investigator is requested to personally hold a workshop under consultation with the Liaison, where the reviewer can evaluate the achievements. J-PARC/MLF may reject the third year of research plan for a Long-Term Project that has not been evaluated or has been evaluated as a non-value project.

Utilization and storage of user-brought instrument

If users bring their instrument for use in their experiment, they are requested to consult the facility on the utilization and storage of the instrument in advance of their experiment. MLF might permit it as a permanent instrument if they can open its use to all MLF users.

If users bring a large instrument, it is necessary to make an agreement between their affiliated institute and the J-PARC Center. If they are willing to develop a new instrument, MLF strongly recommends that they consult with MLF at the design stage.
