Fast Track Proposal

J-PARC MLF offers a mail-in program called Fast Track Proposal for non-proprietary uses (free of charge). The users send their samples to MLF, and MLF staff carry out experiments on the user’s behalf and send the data back to the users. The Fast Track Proposal is only available on SuperHRPD, NOVA, PLANET, SOFIA, SHARAKU, SENJU and RADEN (RADEN is available only for domestic users). Users may download the application form, fill the form, and submit to UO ( at any time. The application will be reviewed for technical feasibility and safety before the proposal is accepted.

In each instrument, peer-reviewed proposals will take precedence over the Fast Track Proposal; the Fast Track Proposal cannot be guaranteed to be carried out at the particular time. The sample will not be sent back: disposal or temporal storage & take-home when the user visits MLF. An experimental report must be submitted to UO within 60 days after the experiment is accomplished or by the next application for Fast Track Proposal, whichever comes first.

Common issues

Aim: a feasibility study before a full proposal, urgent PhD work to complete the thesis, an additional experiment to complete the user’s proposed experiment, etc.
Limit: two days/cycle in all Fast Track Proposals


Experiment conditions: RT, 10 - 300 K within 24 hours
Number of temperature points: consult with instrumental scientists
Samples: send samples (powder form in general) to UO before one week of the Fast Track experiment


Experiment conditions: 20K - 700K within 24 hours (Max no. of sample is 8)
Sample: request sample holders to UO ( Install samples (powder form in general) into the holders, seal them, and return to UO:


Experiment conditions: High pressures up to 7 GPa and RT within 48 hours
Number of pressure points: consult with instrumental scientists
Samples: send powder samples of more than 200mm3 to UO before one week of the Fast Track experiment


Available beamtime: Typically half a day (no sample change), one day in maximum (one chance to change samples).
Experiment condition: Experiments that do not require much sample exchange such as

Sample environment : Equipments provided by the SOFIA are basically available

Sample shipment: Send substrates with films and/or solution for sample treatment to the users office Other notice: Contact the instrumental scientist before submission (especially for experiments requiring special care before and/or during measurements)


Experimental conditions: Room temperature, atmosphere, within 24 h, less than 16 samples
Samples: Solid thin films prepared on circular substrates with a diameter of 50-50.8 mm and a thickness of 1-3 mm made of silicon or quartz


Measurement conditions: Room temperature only
Experiment Time: Beam time per experiment is limited to one day (24h)
Other conditions: Automatic measurements only


FTP application and sample shipment are accepted only from domestic users.
Discussion with beamline scientists is required before proposal submission.

Important Notice for sending your samples from outside Japan

There are regulations covering international shipping of chemicals. All required steps (e.g. paperwork, safety data sheet (SDS), customs procedures, etc.) for the entry of your samples to Japan have to be completed at your own responsibility and expense. MLF cannot assist you with this.

Since it may require a customs clearance procedure, it is recommended that you consult the delivery company.
