Closed: Call for 2023B Proprietary Proposals

Japan Synchrotron Radiation Research Institute (JASRI) is inviting the Proprietary Proposals for the 2023B (October 2023 – February 2024, tentative) and for the first period of 2023B (October – mid-November 2023, tentative). Interested parties are encouraged to apply. Please read the following instructions in full before preparing your application.

     Special Notes 
  1. Special policy will be applied to 2023B term proposals in order to minimize the effects of beamtime cancellations. Please make sure to check here.
  2. Please understand that there is a possibility that we cannot provide stable supply of Helium (both liquid and gas) due to the recent situation regarding global helium supply.

1. Proprietary Proposals

The Proprietary Proposal is for proprietary research recommended for users dealing with confidential information or experimental samples. The submitted proposals are reviewed only from the viewpoint of feasibility, safety, and conformity to the Science, Technology, and Innovation Basic Plan and social norms. A beamtime fee will be charged. Users have no obligation to publish their results.

2. Research Period

[At Beamlines with biannual calls for proposals]

 From October to late February 2024 (tentative)

[At Beamlines with sixannual calls for proposals]

 From October to mid-November 2023 (first period of 2023B)
 Please note that proposals requiring special conditions, such as bunch mode designation, may not necessarily be assigned to this research period.

3. Beamlines and Beamtime Available to Users

* 1 shift is 8 hours and for any proposals that are allocated by the hour, the fees are charged by the hour.

* Program Fee: 80,000 yen/shift for CryoTEMs


9.1 Special Note for Proposals for BL47XU

The BL47XU will allocate a few shifts for the 2nd and the 3rd period to the proposals that fit the following conditions:
A. The research in Industrial Application using the imaging devices at BL47XU.
B. The application includes at least one person out of a project leader and project team member who is an employee of a private company or affiliated institution.
