Proposal Submission and Assessment Procedures

Submission procedure

Applicants are requested to submit proposals via the online J-PARC Proposal System.

The principal investigator is requested to complete user registration as follows before proceeding to the proposal application.

  1. Access J-PARC Proposal System and register as a new user.
  2. A USER ID and temporary password are sent to you by e-mail. Please log in with this information and change the temporary password to a password of your choice.
  3. Please fill in the applicable application form for after completing the login process.

    Users who have previously submitted a proposal via this proposal submission system can use the data from this proposal in sebsequent proposals.
    A submission acceptance email is sent to you when the electronic application form has been successfully sent. Please confirm your submission in the e-mail message.

Assessment procedure

All nonproprietary proposals are reviewed and ranked by the Neutron and Muon Program Review Committees which are organized under the MLF advisory board. These are also sub-committees of the Neutron and Muon Program Review Committees to assess proposals from specialized viewpoints. A list of sub-committees can be seen below.

List of keywords for each sub-committee is also available.

Principal investigators wishing to apply for the Industrial Applications (P7) review field must belong to a private company. Users wishing to apply for the Industrial Applications (P7) review fiels are recommended to consult the MLF about their experiment plan prior to submitting their proposals. [Contact for technical consultation]

Only users who have wishing to apply for previously applied for the New User Promotion at CROSS-Tokai are able to choose the New User Promotion (P9) review field.

The review of urgent proposals is conducted by the director of MLF division in cooperation with the chairperson of the MLF-PRC and the person responsible for the instrument to be used for the proposed experiment. The review results are approved by the director of the J-PARC center and before the principal investigator of the proposal is notified of the outcome.
Principal investigators of urgent proposals must submit an experiment report to the MLF-PRC after completion of the experiment.
Users wishing to apply for the "Industrial applications (P7)" are recommended to consult the experimental plan with MLF prior to submitting proposals.

Reviews of rapid access proposals are conducted by an e-mail based discussion among members of MLF-PRC.
Principal investigators of the rapid access proposals must submit an experiment report to the MLF-PRC after completion of the experiment.

Evaluation criteria

Submitted proposals are assessed and selected based on the following criteria:

For project use proposals, the evaluation criteria also includes necessity and justification of the project use and the feasibility of the project members.

For instrument use proposals, the evaluation criteria also includes the capabilities of the instrument group for improving performance of the instrument, appropriateness of budget profile and justification of the cutting-edge research and development.

Safety review

Safety aspects of all proposals are reviewed by a safety review team from the Materials and Life Science Division of the J-PARC center.

Information of experiment sample(s)

Please provide chemical information on the experiment sample(s) in the application form. A review of chemical and radiation safety is conducted by the J-PARC Center.

At present, the following rules apply for MLF:

  1. Powder samples must be sealed in a vanadium cell
  2. Liquid samples and samples contained in a capillary with a solution/solvent must be checked by the J-PARC radiation control office for approval before use.

Users planning to use sample cells and/or capillaries are therefore requested to provide information on them so that the consultation process can poceed smoothly.
