Call for Proposals for 2024B SACLA Feasibility Study Program

April 18, 2024

The Japan Synchrotron Radiation Research Institute (JASRI) is pleased to announce a call for 2024B SACLA Feasibility Study Program to provide an opportunity to experience the use on a trial basis for the purpose of dissemination and enlightenment at SACLA. Please refer to the following guidelines and instructions to apply.

General Information

  1. Subject of the program
    Sample screening and feasibility study using the following instruments.
    From the call for 2023B, the Program also accepts proposals related to the studies of the structure of microcrystalline materials in addition to those of proteins using DAPHNIS for serial femtosecond crystallography.

    • (1)DAPHNIS for serial femtosecond crystallography (SFX) [Tono et al., J. Synchrotron Rad. 22, 532 (2015)]
      • X-ray diffraction measurement of micrometer-sized crystals
      • Powder diffraction measurement of nanometer-sized crystals

      Pump-probe experiments using optical lasers are not included.

    • (2)Experimental platform using the high-power nanosecond laser [Inubushi et al., Appl. Sci. 10, 2224 (2020)]
      • Ultrafast X-ray measurements of matter under pressures of sub-terra Pa ranges generated by laser-induced shock waves.

      Please refer to the description on the high-power nanosecond laser system (HERMES) below.

    Please note that we may not be able to fulfill your request on experimental conditions due to the beamtime schedule.

  2. Allocatable beamtime
    The maximum beamtime is 1 shift (12 hours).
  3. Co-applications with the SACLA Research Proposals
    The Feasibility Study Programs and the SACLA Research Proposals can be applied simultaneously. If you apply both with the same contents, you do not need to submit the application form for the SACLA Feasibility Study Program. Instead, please put a checkmark on the corresponding item in Term 5 (Co-Application with Feasibility Study Program) of the application form for the SACLA Research Proposals. In this case, the submitted proposal is reviewed as the Feasibility Study Program only when your SACLA Research Proposal is rejected.
  4. Publication of results
    Publication as peer-reviewed papers is not required for research results obtained through the Feasibility Study Programs. Project leaders must submit Experiment Summary Reports within 60 days after completion of the experiment. The Experiment Summary Reports will be public online.
  5. High-power nanosecond laser system
    Osaka University had deployed a high-power nanosecond laser system (HERMES) at SACLA. An experimental system is available at BL3 EH5 for advanced pump-and-probe experiments with the XFEL and the high-power nanosecond laser.
    Applicants/project leaders who apply for the above experimental system are required to consent to the following matters before submitting their programs.

    • (1) Any program using the above experimental system is also regarded as a proposal for Collaborative Research of Institute of Laser Engineering (ILE), Osaka University.
    • (2) JASRI provides information given in a program to ILE if the program is approved.
    • (3) Applicants/project leaders shall state in presentations and publications that the results were obtained by using both the SACLA XFEL and the high-power nanosecond laser system of ILE, Osaka University.
    • Applicants/project leaders should contact the XFEL Utilization Division (mail to: in advance of the program submission for the information of the experimental system and its capabilities.
      Please note that the typical operating conditions of the laser system in 2023B were as follows.
      – Pulse energy: ~15 J on sample
      – Pulse shape: 5 ns square pulse
      – Central wavelength: 532 nm
      – Focused beam profile: flat-top profiles with a diameter of ~120, ~170, ~260 or ~470 µm (FWHM) using a diffractive optical element (DOE).

1.Types of Programs

Call for 2024B SACLA Feasibility Study Programs at SACLA

  • Feasibility Study Programs: Screening of samples, measurement conditions and feasibility studies

Once approved for beamtime, programs are valid for only 2024B.

2.Applicant Eligibility

There are few restrictions on the eligibility of applicants:

  • Students are ineligible (however, students can participate as project team members in any Feasibility Study Program).
  • If you are affiliated with an institution outside Japan, please have at least one local contact person that is affiliated with a Japanese institution participate in your experiment. If you cannot find one, please contact the Users Office (

3. Target Beamlines and Instruments

The target beamlines and instruments of this program are;
 – Experimental platform for Serial Femtosecond Crystallography (SFX) at BL2 or BL3
 – Experimental platform for pump-and-probe measurements with the XFEL and the high-power nanosecond laser at BL3

For details of those instruments, please see the Beamline Technical Information for SACLA HP at the following link:

4. Program Period and Beamtime Allocation

The program period extends from September 2024 through February 2025* (excluding scheduled maintenance periods).
During this period, the facility will operate around the clock with user beamtime allocated for successful program and proposals.
For SACLA beamlines, the beamtime for Feasibility Study Programs is basically allocated by max 1 shift (12hours).
*Subject to change, due to budgetary constraints.

5. Fees

There is no charge for SACLA Feasibility Study Programs, neither Beamtime Fee nor User Fee.

6. Application and Required Procedures

Applicants/project leaders are required to submit applications via the SACLA User Information website (SACLA UI site:

  1. User Registration
    To submit an application, user accounts (i.e., user ID and password) for SPring-8/SACLA are required for all participants of the experiments. For registration, please visit the website: Before starting the application process, project leaders must ensure that all project team members have completed user registrations.
  2. Application Method
