Call for Proposals using the Photon Factory
IMSS publicly calls for the experiment proposals in which no less than two of the four beams, synchrotron radiation at PF, slow positron at the Slow Positron Facility, neutron and muon beam at the Materials and Life Science Experimental Facility (MLF) in J-PARC, are required to be used, as Multiprobe Experiment from 2015. For more details click below link.
Call for Proposal - Multiprobe Experiment(IMSS)
Guidelines for filling the application form
- All application should be done by "KEK Proposal Submission System" (except Type S1). Please refer to the instruction and/or the operation manual on the system.
- A proposal is mainly evaluated based on its scientific merit and technical feasibility of the research plan. You should clearly express what you plan to carry out during the valid term of the proposal.
- The application will be reviewed based on the description on the form. Please include a full description of the experiment.
- Proposals including two or more projects which do not have strong scientific relation should be submitted separately. For example a proposal including protein A and protein B that have little biological relations, should be divided two independent proposals.
- Please fill application in either English or Japanese.
A simple and concrete title is required (not comprehensive). Imagine the title that may be used in a paper for the result.
Please indicate the research field of your proposal referring to the "Research Field" below. The multiple numbers can be applied.

||Life science I
||Life science II
||Life sciences other than protein crystallography, and research on soft matters by the method of SAXS.
||Methods, instrumentation and detectors
Proposals of "Methods and instrumentation, detectors" will be reviewed in the most relevant field among the other fields.
Contact Person in Japan (CPJ)
Overseas applicants are required to assign a contact person to act as an intermediary with the Photon Factory. His/her approval to act as CPJ is obligatory. The contact person should live in Japan and be a Japanese speaker. The contact person will ensure that the application procedure runs smoothly, and will also assist with visa procedures, reservation of accommodations etc. If you do not know any appropriate person for the Contact Person, the person in charge of the station you want to use can help you find candidates for CPJ.

Proposal review and scoring
Proposals are reviewed by referees, then in the Photon Factory Program Advisory Committee (PF-PAC). Proposals are scored between 5 and 1 (5 is the highest). Those above threshold are approved by PF-PAC. A proposal is evaluated based on its scientific and technical merit, technical feasibility of the research plan and capability of the experimental group. The approval of a proposal means that it is evaluated to be worth doing by PF-PAC. However, please mind that the "approval" does not always guarantee the allocation of beam time you wrote in the application form.
PF-PAC pays more attention to the productivity of the proposing user groups when reviewing the proposals.
In case a spokesperson has more than three approved proposals that validity periods were expired between 1 year and 6 years ago from when the applied proposal becomes active,
- Spokespersons who haven't registered their publications on more than half of the approved proposals are asked on the reason why they haven't done yet.
- According to the reply, PF-PAC analyzes the reasons and considers the score.
- Proposals without any reply to the inquiry are rejected.
