On September 26, Geelong announced that its wholly-owned subsidiary, Kunshan Guoli High Power Device Industrial Technology Research Institute Co., Ltd. (referred to as "Guoli Research Institute"), has received the "Winning Bid Notice". Guoli Research Institute is the winning unit of the "Chinese Academy of Sciences Institute of High Energy Physics CSNS-II Superconducting Elliptical Cavity and Beam Dump 648MHz Klystron Purchase Project (Second Phase)", with a winning bid price of 56.577 million yuan.

Located in the Songshan Lake area of Dongguan, the China Spallation Neutron Source (CSNS) is a major scientific and technological infrastructure project constructed during the "12th Five-Year Plan" period. As China's first and the world's fourth pulsed spallation neutron source, the facility was planned since July 2000, the foundation stone was laid in October 2011, and the first phase of the project passed the national acceptance in August 2018 after nearly 20 years. At the beginning of this year, the construction of the second phase of the CSNS project officially started. It can be foreseen that when the CSNS second phase is operational, this large scientific device will greatly meet the national strategic needs and the demands of world-leading research on high-performance neutron scattering. It will serve as a powerful tool in exploring the frontier of science, addressing critical scientific issues in national industry development, and will undoubtedly be the core engine of innovation and development in the country.

The CSNS Phase II upgrade project will use superconducting accelerators to increase the beam energy by about 4 times. The superconducting elliptical cavity and beam dump 648MHz klystrons will be provided by the Guoli Research Institute. The 648MHz high-power klystron is a key core component of the CSNS Phase II upgrade project's linear accelerator, undertaking the important task of providing energy to 24 648MHz superconducting elliptical cavities and 2 beam dumps of the linear accelerator, serving as the power source of the linear accelerator. This provision of the 648MHz high-power klystron for the Chinese Academy of Sciences Institute of High Energy Physics is a full demonstration of the company's research capabilities, technological level, and manufacturing capabilities being recognized, further consolidating the company's leading position in the field of large-scale scientific projects.
