| PDF : Detailed Programs of Breakout Sessions |
| A1: Synchronized optical lasers |
| “Capability of time-resolved experiments using optical and XFEL pulses” |
| Organizers: T. Sato (LCLS) and T. Togashi (SACLA) |
| Synchronized optical lasers are significant for opening up the new scientific capability with time-resolved measurements in XFEL. In this session, the following issues are going to be discussed for the precise operation of the optical lasers in each XFEL facility. |
| •Precise synchronization and timing control |
| •Short pulse operation |
| •Expanding wavelength region, MIR, THz |
| •Scientific capability for pump-probe experiments |
| A2: High-power optical lasers |
| “Experimental platforms with high-power optical lasers: current and future” |
| Organizers: N. Ozaki (Osaka Univ.) and K. Sueda (SACLA) |
| As the main goal, this breakout session will discuss future improvements and upgrades to the experimental platforms with high-power optical lasers (nanosecond/femtosecond lasers) at SACLA. As an introduction, the current status and capabilities of the platforms will be introduced from the facility, followed by the reports on the typical experimental methods and recent results from the representative users. A virtual tour of the platforms is arranged at the end of the session. |
| A3: Detectors |
| “Current status and prospects of X-ray detectors at SACLA” |
| Organizers: T. Hatsui (SACLA) and T. Osaka (SACLA) |
| This breakout session aims to share the current status and prospects of X-ray detectors at SACLA. In the initial part of the session, SACLA staff overview detectors currently available at SACLA and introduce specifications of new detectors underdeveloped, such as CITIUS. Then, representative users from various scientific fields will share how to use them and analyze experimental data, and make requests on the new detectors for improving data quality and opening up new opportunities. Participants will be encouraged to provide feedback, inputs, and ideas to the facility in the round table discussion. |
| B1: Hard X-ray FEL beamlines (BL2/3) |
| “Short- and long-term requirements from users for hard X-ray beamlines” |
| Organizers: Y. Nishino (Hokkaido Univ.) and I. Inoue (SACLA) |
| This breakout session aims to discuss future directions of hard XFEL beamlines (BL2 and BL3). In the initial part of the session, SACLA staff member reports (i) recent activities for generating tailor-made XFEL beams via machine-learning techniques and (ii) technical seeds for future source developments (high flux, high photon energy, short pulse, high repetition rate, etc.). Then, representative users from various scientific fields will identify present limitations and future prospects of XFEL experiments and make requests for improvement of photon beam qualities in future source upgrades. Participants will be encouraged to provide feedback, inputs, and ideas to the facility in the round-table discussion. |
| B2: Soft X-ray FEL beamline (BL1) |
| “Advanced science by frontier spectroscopies with soft X-ray FEL” |
| Organizers: I. Matsuda (Univ. Tokyo) and Y. Kubota (SACLA) |
| Soft X-ray FEL (SXFEL) is an ultrahigh brilliant soft X-ray source with ultrashort pulse-width, ultrahigh spatial coherence, and tunability of photon energy. At SACLA SXFEL beamline (BL1), novel experimental techniques are developed to unveil unique electronic states in matters. In this breakout session, the recent achievements will be presented and their future uses will be discussed with participants, including distinguished researchers from various fields. |
| B3: Experimental support and information sharing (Language: Japanese) |
| “Enhancement of user supports for efficient production of outstanding research results” |
| Organizers: H. Yoneda (UEC) and Y. Inubushi (SACLA) |
| The session aims to discuss user support including the information provision and the experimental assistance for the efficient production of outstanding research at SACLA. The support activities will be presented from the SACLA facility members and suggestions to the facility will be proposed from the users of several scientific fields. We will expect inclusive discussions to promote future SACLA facility in this breakout session. Please note that the language of this particular session is Japanese. |
