Organized by the National Synchrotron Radiation Research Center (NSRRC), the annual Users’ Meeting & Workshops is one of the biggest and the most important meetings in the field of synchrotron radiation in Taiwan. Each year, it has approximately 250 poster presentations and attracts over 400 participants. The 30^th Users’ Meeting & Workshops is scheduled to take place from October 31^st to November 2^nd, 2024. The User Executive Committee (UEC) of the NSRRC sincerely invites you to attend the event and present your research results. The three-day program will be packed with excitement, featuring invited talks by outstanding users and various opportunities for participants to discuss and exchange ideas. We heartily welcome your participation. The program is briefly summarized below.

Day 1: October 31^st (Thursday)

• The NSRRC management will brief users on the "Current Status and Future Prospects."
• President Chi-Hung Lin of National Yang Ming Chiao Tung University, who holds an MD/PhD in Microbiology & Immunology, will deliver a plenary talk.
• Outstanding users will be invited to present their latest innovative work.
• Authors who have excelled in the first-round pre-evaluation will proceed to the "English Oral Presentation" competition.
• The "Town Meeting" features updates from the UEC and Neutron UEC chairpersons, along with NSRRC management addressing user-related issues and facility development.
• During the evening "Poster Session," all posters and presenters will be accessible on-site for evaluation, sharing, and discussion.

Day 2: November 1^st (Friday)

• The well-received "NSRRC Run" will allow participants to break a sweat and take in enjoyable settings of the NSRRC campus.
• Outstanding users will be invited to present their latest innovative work.
• The "NSRRC Outstanding Paper Award," promoting synchrotron radiation science in Taiwan, will acknowledge scientific achievements in applied sciences this year, with the recipient presenting their award-winning work.
• All attendees are invited to the banquet for networking and celebration. Winners of posters and oral presentations will be honored.
• Four mini workshops will be organized concurrently:
  1. Unveiling Molecular Structures and Self-assembly via X-ray Scattering and Simulation
     This mini workshop focuses on recent advancements in instrumentation and data analysis techniques for elucidating the structures and self-assembly behaviors of biomolecules and polymers through X-ray scattering methods, complemented by molecular simulations. Cutting-edge topics include SWAXS-driven molecular dynamics simulations, in situ Rheo-SWAXS, and imaging with small-angle scattering and coherent diffraction.
  2. X-ray Emission Spectroscopy Interest Group (XES)
     Hard X-ray Emission Spectroscopy (XES) is a powerful tool for investigating the electronic structure of materials, providing insights into occupied valence states and detecting local spin angular momentum, making it invaluable for magnetic characterization in spintronics and systems such as spin catalysts. Utilizing the superior light source of TPS, we plan to develop XES-related beamlines and endstaions to enhance the capabilities of our user community. This mini-workshop will include presentations by leading domestic experts with practical experience in using XES techniques, as well as updates on the design and construction progress of the proposed beamlines and enstations.
  3. SPEM discussion: Past, Future and Beyond
     Since 2000, the TLS 09A1 SPEM beamline has served the scientific community for 24 years. Now, with aging equipment and technological advancements, NSRRC has built TPS 27A2 and TPS 39A2 with capabilities that surpass those of SPEM. This workshop will showcase SPEM's evolution, introduce the advanced facilities of the new endstations, and discuss their role in future scientific innovation. Through deep interaction and exchange of ideas with users, we aim to gather feedback to guide facility upgrades, ensuring smooth transitions to new platforms. Emphasis will also be placed on the importance of technology transfer and laboratory support to propel a new chapter in science.
  4. THz Beamline User Promotion Meeting
     Coherent THz sources based on linear accelerator technology have been established at the NSRRC. These sources offer intense output, tunable wavelengths, and superior temporal coherence, making them highly valuable for applications in semiconductors, quantum materials, and biomedical imaging. Additionally, the photo-injector system provides high-quality sub-picosecond electron sources. This mini workshop aims to promote the coherent THz sources and high-brightness photo-injector system. Researchers in the field will share their studies and provide suggestions on the specifications of the THz sources. We hope to attract more users interested in utilizing these advanced THz sources.

Day 3: November 2^nd (Saturday)

Two workshops will take place in parallel.

• Workshop I：Semiconductor Industry Application Workshop
  In the 21st century, Taiwan's semiconductor industry stands as a global leader, holding significant sway in the world economy. Synchrotron-based techniques have proven to be powerful tools for semiconductor engineering R&D, providing solutions to critical problems and conducting precise analyses of crystalline phases, energy band structures, surface/interface morphologies, and elemental bonding environments in semiconductor thin films. This accelerates the development of next-generation materials for various applications. This workshop aims to gather industry elites and academic experts to explore the applications of synchrotron light source technology in semiconductors, fostering collaboration opportunities between industry demands and research endeavors.

• Workshop II：Inelastic Neutron Scattering Study and SIKA applications
  SIKA, Taiwan's first self-designed and built cold neutron triple-axis spectrometer, specializes in non-elastic scattering research, aligning with local research trends and supporting industrial R&D. This workshop will gather renowned scholars, both domestic and international, to share their research experiences with SIKA across superconductors, quantum materials, magnetic thin films, energy materials, and more. Through this event, we aim to foster direct communication, collective brainstorming, and the effective utilization of advanced neutron scattering technologies to enhance domestic academic research and industrial competitiveness on a global scale.

We welcome colleagues from the scientific community to sign up for the event. Please complete the online registration (https://nsrrc-usermeeting2024.conf.tw/to?en) by August 23^rd (Friday).

Looking forward to seeing you at the meeting!
