Dear MEDSI2023 Delegates,

First of all, on behalf of the Institute of High Energy Physics, Chinese Academy of Sciences, we would like to extend our heartfelt gratitude to you for your participation at the 12th International Conference on Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation (MEDSI2023) which was held from November 6 to 10, 2023, in Beijing China.

In the 5-day Conference, 370+ participants from 21 countries and regions registered. Speakers of 5 keynote talks, 37 contributed oral talks, and 150+ poster presenters presented their recent scientific achievements. We all have been inspired by the rapid advances in the field of synchrotron radiation and free-electron laser light sources worldwide, and deeply impressed by active academic exchanges between participants from different countries and regions. Your participation has made MEDSI2023 a great success.

It is worthwhile to mention the special support of JACoW team and our sponsors and exhibitors and the companies for their involvement in the academic activities of MEDSI2023 in different manners.

It is indeed our great honor for IHEP and HEPS to host the MEDSI2023. Confucius once said, "It's a pleasure to have friends coming from afar". We look forward to seeing you again in the near future.
