Call for 2019B Proposals at SACLA


The Japan Synchrotron Radiation Research Institute (JASRI) is pleased to announce the call for 2019B proposals for research to be carried out at SACLA. Please follow the following guidelines and instructions to apply.

Important Notices

  • Publication of research results
    Applicants who have used SACLA should describe their publication status in “Progress Report” (page 6 of the proposal template). The record of peer-reviewed publications related to researches at SACLA is important information for the Review Committee to evaluate the proposal. Publications of SACLA research results should be clearly distinguished from those of other relevant researches.
    It is mandatory to publish research results obtained through the use of SPring-8/SACLA within three years from the end of the half-year research term.


  • The budget support of the SACLA User Fees for non-proprietary research submitted by users from foreign organizations will be ended from 2019B.
    Please refer to the following link for details of “User Fees.


  • Self-seeded XFEL
    A reflection self-seeding system is available at BL3. A bandwidth of self-seeded XFEL can be much narrower than that of SASE XFEL, while an average pulse energy is comparable. A typical setup time for seeded XFEL is 1 shift, which will be included in a user’s beamtime. Please also note that it takes more time to change wavelength of seeded XFEL than in the standard SASE case. Those who plan to use self-seeded XFEL should contact the XFEL Utilization Division ( in advance of the proposal submission to obtain the detailed information of the operation conditions.
  • Experiments at BL2
    The following experiments are basically conducted at BL2:
    – Serial Femtosecond Crystallography (SFX)
    – Fixed-target Protein Crystallography (FPX)
    – Coherent Diffractive Imaging (CDI)
  • Feasibility-Check Beamtime (FCBT)
    We may accept a request of a feasibility-check beamtime (FCBT, max 0.5 shifts) for sample screening before the main experiment. Please note that the feasibility-check can be performed under the following conditions during FCBT for the time being:
    – Beamline & experimental hutch: BL2 EH3
    – Experimental system: DAPHNIS (J. Synchrotron Rad. 22, 532-537, 2015)
    – Standard photon energy: 7 keV or 10 keV (pink beam)
    – X-ray spot size: 1-2 um (with the 1-um focusing system at EH3).
    Those who require the feasibility-check beamtime should provide the reasons in their proposal.
  • Upgrades of BL1
    A timing monitor system is available for user experiments at BL1 from 2018B term. A plane mirror is installed to keep the focused-beam axis horizontal after the KB mirrors. Due to this modification, the beam height becomes ~1250 mm from the floor at the focal point, which is ~245 mm lower than the previous height. Unfocused beam is not available for user experiments.
  • New instruments
    The following instruments are available for user experiments. Each instrument will be operated under limited conditions for the time being. Those who plan to use the instruments must contact the XFEL Utilization Division ( in advance of the proposal submission to obtain the detailed information of the operation conditions.

    • Nano-beam coherent diffraction imaging (CDI) system (MAXIC-S)
      The MAXIC-S has been developed in collaboration with the Prof. Yoshinori Nishino’s group of Hokkaido University as a CDI experimental system using 100-nm focused XFEL beam. This system is available at BL2 EH3/4b.
    • Split-and-Delay Optics (SDO)
      An SDO system has been developed in collaboration with the Prof. Kazuto Yamauchi’s group of Osaka University. The SDO system produces double monochromatic XFEL pulses with a time separation up to 100 ps. This system is installed in the optics hutch of BL3 to be available at all the experimental hutches of BL3.
    • An experimental chamber for the combination use of XFEL and high-power nanosecond laser system
      Osaka University had deployed a high-power nanosecond laser system at SACLA. To perform advanced pump-and-probe experiments with the laser and XFEL, we have developed a new experimental chamber in consultation with researchers in the field of high energy density science, particularly with the Prof. Ryosuke Kodama’s group of Osaka University. This chamber is available at BL3 EH5.
    • High-Power Femtosecond Laser System at BL2 EH6
      A high-power femtosecond laser system with the maximum power of 500 TW will be operated under limited conditions for the time being. Approved beamtime might be allocated on a “single-shift-in-a-day” basis (described below) depending on the laser operation situation even if it is not requested in the proposal.

  • Beamtime on a Single-shift-in-a-day Basis at BL2
    We start a trial of beamtime allocation on a single-shift-a-day basis (one shift is 12 hours from 10 am – 10 pm or 10 pm – 10 am) only when there are appropriate scientific/technical reasons. Those who require such beamtime allocation should describe the reasons in the “Details of requested shifts” section, and fill the section of the “Number of Shifts Requested” as an example below:
    (Example) 1 shift x N run
    Please note that the day-shift or night-shift cannot be specified in the proposal. Another group may conduct experiment in the other shift on the same day. In such case, machine tuning time may be necessary in every shift. The request may not be fulfilled to maximize the effective use of SACLA beamtime opportunity.
