Yes, it is possible to take a tour of J-PARC even if you are not participating in any experiments. Please follow the procedure outlined hereto arrange your visit.

You can apply to use the experimental equipment by submitting a "Proposal" through the designated website during the proposal call period. If you need support with planning your experiment or navigating the application process, please feel free to contact the CROSS User Support Desk — we will be happy to assist you. For more information on the overall application process, please refer to this page.

A call for proposals is the period during which applications are accepted for the use of experimental equipment. Since Proposals are categorized based on the nature and duration of the experiment. For more details, please refer to the "Call for Experimental Proposals" page.

It depends on the type of experiment you plan to conduct. General proposals are accepted once or twice a year during specific call periods, each lasting about three weeks. On the other hand, urgent access proposals and New User Promotion (NUP) proposals may be submitted at any time. For more details, please see "this page."

Eligible users include beamline users at J-PARC, staff members of CROSS, personnel from J-PARC and MLF, as well as other individuals in similar roles.
