China High-Intensity Accelerator Technology Developments for Spallation Neutron Source and Accelerator Driven Systems J. Wei1 and S. Fu2 1Tsinghua University, China Corresponding Author: weij@tsinghua.edu.cn During the recent years, there have been aggressive developments in China on the technology of high intensity hadron accelerators for the spallation neutron source, accelerator driven systems (ADS), and related programs including hadron therapy. For example, the China Spallation Neutron Source (CSNS) is a newly approved project to be constructed in Guangdong, China. The CSNS complex consists of an H- linear accelerator, a rapid cycling synchrotron accelerating the beam to 1.6 GeV, a solid tungsten target station, and five instruments for spallation neutron applications. The facility operates at 25 Hz repetition rate with an initial design beam power of 120 kW and upgradeable beam power of 500 kW. The primary challenge is to build a robust facility at a fraction of the “world standard” cost. Benefiting from a close collaboration with world leading institutes and facilities, tremendous efforts were made in China to develop domestic vendors to comprehend the technology for key systems of high intensity ion source, linear accelerators, and rapid cycling synchrotron. Goals of such facilities include spallation-neutron-based, muon-based, and proton-based platforms for multi-discipline science and industrial applications, fast-neutronbased platform for nuclear science and applications, and parasitic apparatus for medical therapy and ADS tests. This paper attempts to summarize the R&D efforts, key component prototyping and vendor development experience, and user development efforts during the past several years in China.
