NSRRC Activity Report 2022

Facts and Figures 127 Minisymposium on Crystallography Domestic participants from academic, medical, and industrial sectors exchanged their experiences of establishing radiotherapy facilities at the 2022 Workshop on High-Energy Medical Accelerators for Particle Therapy. The Minisymposium on Crystallography was held online by the NSRRC on May 21. The symposium began with a presentation on the dynamic structure of electrocatalysts using X-ray absorption spectroscopy by Prof. Hao-Ming Chen of NTU. Subsequently, Dr. Meng-Chiao Ho (Academia Sinica) gave a talk on the present and the future of crystallography in electron microscopy. Dr. Frodo Chao of the NSRRC then introduced the NSRRC Protein Diffraction team to the participants of the minisymposium. The participants acquired useful information through discussions with the NSRRC scientists. 2022 Workshop on High-Energy Medical Accelerators for Particle Therapy The 2022 Workshop on High-Energy Medical Accelerators for Particle Therapy was held on October 15 at the NSRRC. Co-organized by the NSRRC and Taipei Veterans General Hospital (TVGH), this was the first workshop that focused on the planning, installation, commissioning, operation, and maintenance of medically oriented accelerators in Taiwan. Three types of radiation therapies are commonly applied in cancer treatment: photon therapy, proton therapy, and boron neutron capture therapy. TVGH introduced heavy ion radiotherapy to Taiwan’s medical industry through consultation with the NSRRC regarding its planning, operation, and maintenance and thereby increased the variety of available radiation therapies and became the first institution to use medically oriented heavy ion accelerators in Taiwan. During the workshop, speakers from NTHU and the NSRRC gave presentations on the shielding of particle therapy facilities and the application of accelerators for FLASH radiotherapy; speakers from several hospitals shared their experiences of establishing the Heavy Ion Therapy Center at TVGH; the Radiation Science and Proton Therapy Center at the NTU Cancer Center; the Proton and Radiation Therapy Centers at Chang Gung Memorial Hospital and Kaohsiung Chang Gung Memorial Hospital; and the Proton Centers at Taipei Medical University Hospital, China Medical University Hospital, and Taichung Veterans General Hospital. Participants of the workshop also visited the accelerators and research facilities of the NSRRC. This workshop was an opportunity for the 98 participants from academic, medical, and industrial sectors to work toward developing a more comprehensive health-care system. NSRRC Focus Forum at RPGR 2022 Conference The 13 th Recent Progress in Graphene and Two-dimensional Materials Research Conference (RPGR 2022) was held from November 13 to 17 at Chang Yung-Fa Foundation International Convention Center in Taipei. One of the Focus Forums on November 16, which was entitled “What/How Can NSRRC Help in 2D Material Research?,” was co-organized with the NSRRC. During this forum, four NSRRC scientists shared the studies on research on two-dimensional materials involving NSRRC experimental techniques, including angle-resolved photoemission spectroscopy, synchrotron radiation spectroscopy, photoelectron momentum microscopy, and far-ultraviolet spectroscopy. The presentations were followed by a panel discussion on optical properties, electronic structures, and energy applications.
