[Updates for 2023B]

• Response to Review Comments
  If applicants/project leaders have received the review comments in past applications, it is required to respond to them in the field of “the preparation status related to this application proposal” in the application form. The past review results can be found with the review comments on the SACLA User Information website (SACLA UI site) My Page for the last five terms.
   
• Target Expansion of the SACLA Feasibility Study Program
  SACLA Feasibility Study Program provides an opportunity to experience the use of SACLA on a trial basis. From the call for 2023B, microcrystalline materials are newly added to the targets of the feasibility study using DAPHNIS for serial femtosecond crystallography. Please refer to the following link for the details.
  https://sacla.xfel.jp/?page_id=16958&lang=en
   
  The SACLA Research Proposals and the Feasibility Study Program can be applied simultaneously. If you apply both with the same contents, you do not need to submit the application form of the Feasibility Study Program. Instead, please put a check mark to the corresponding item in Term 5 (Co-Application with Feasibility Study Proposals) of the application form of the Research Proposals. In this case, the submitted proposal is reviewed as the Feasibility Study Programs only when your Research Proposal is rejected.
   

[Experimental instruments/operation modes that need prior confirmation]

• List of the experimental instruments/operation modes
  The following instruments or XFEL operation modes are available for user experiments. Those who plan to use the instruments or operation modes are requested to contact the XFEL Utilization Division (mail to: sacla-bl.jasri@spring8.or.jp) to clarify the feasibility with the facility staff well in advance of the proposal submission.
  The typical operating conditions of those instruments or XFEL modes are summarized on the webpage. Please contact the XFEL Utilization Division (mail to: sacla-bl.jasri@spring8.or.jp) to obtain up-to-date information for the 2023B term.
  • Two-color XFEL
    Double pulse XFEL with two different photon energies are available at BL3. The time separation between the two pulses can be varied up to about 300 fs. The maximum time separation and the photon energies have some restrictions.
  • Reflection self-seeding system
    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.
  • 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.
  • Sub-10 nm focusing system
    A focusing system of XFEL (9 keV) down to the sub-10 nm level has been developed in collaboration with the Prof. Kazuto Yamauchi’s group of Osaka University at BL3 EH4c. Since the system is strictly dedicated to experiments using the ultra-high-intensity XFEL, there are severe restrictions on the sample environment and detector arrangements.
  • 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.For details, please contact here.
  • General purpose experimental system for soft X-ray FEL opto-spintronics
    An experimental system with a sub-micrometer focusing Walter mirror has been developed in collaboration with Prof. Iwao Matsuda’s and Prof. Hidekazu Mimura’s groups of the University of Tokyo. The system is available at BL1 for the observation of optical effects such as nonlinear optical phenomena and resonant magneto-optical Kerr effect. Some restrictions may apply in operation conditions because the system is operated on a trial basis for the time being.
  • Broadband terahertz pulses
    Broadband THz pulses from air plasma generated by the synchronized femtosecond laser system are available at BL3 EH2/4c. The center frequency and field intensity at focus are estimated to be around 1 THz and a few hundred V/cm, respectively. Since the operation will be on a trial basis for the time being, the THz parameters are subject to change. Please note that tuning time for the THz pulses is considerably longer than that for the standard laser operation. The tuning time is included in a user’s beamtime.
  • 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. To ensure enough time for the tuning, maintenance, and upgrade of the laser system, the amount of beamtime is limited. We can approve at most about two of the proposals that require the laser system in 2023B.
• 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 proposals.
  (1) Any proposal 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 proposal to ILE if the proposal 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 (sacla-bl.jasri@spring8.or.jp) in advance of the proposal submission for the information of the experimental system and its capabilities.
  Please note that the typical operating conditions of the laser system in 2022B 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 or ~260 µm (FWHM) using a diffractive optical element (DOE)

[Other Notices]

• 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: 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 put a check mark to the corresponding item in Term 5 (Co-Application with Feasibility Study Proposals) of the application form of the SACLA Research Proposals.
   
• Remote Experiments
  A remote-operation system allows users to control experimental instruments from outside the facility. The remote system will be available for some types of experiments. The availability of the system for a specific experiment will be determined based on the status of system preparation and the experimental conditions.
   
• SACLA High Performance Computer (HPC)
  Most of the SACLA users need the SACLA HPC to analyze experimental data taken with standard detectors of SACLA. Please specify the name and the email address of the person whom the facility staff should contact about the SACLA HPC, in the “Facility instruments to be used” section of the proposal. The contact person can be either the project leader or a project team member of the proposal.
   
• Beamtime on a Single-shift-in-a-day Basis
  We may allocate beamtime on a single-shift-a-day basis (one shift is 12 hours from 10 am to 10 pm or 10 pm to 10 am) for technical/operational reasons.
