低能粒子加速器虚拟设计

As the development of the particle accelerator technology, the limitation of the present design methods that mainly depends on the numerical technique emerges gradually. Firstly, because most of the existing codes are developed according to different requirements and the analysis object is aimed to some parts or functions, it is difficult to carry out optimization of the holistic accelerator. Secondly, since these codes are usually developed based on ideal models, it is difficult to solve complicated practical engineering problems such as thermal distortion and mis-machined tolerance; and the nonlinear influence between intense charged beam and instrument is not taken into account. Thirdly, these existing programs are often too complex to use and the computing results are difficult to understand for the designers. Finally, while the investigation of the current method is focused on the design process, less attention is paid to the other processes of the lifecycle of an accelerator such as manufacture, assembly, operation and maintenance. Problems that happen only in the assembly or operation process can not be found in the design process, which might bring on great loss. Therefore, it is difficult to carry out innovative design by use of the present method due to long design period, big design expense and high design venture..In this project, based on the existing analysis codes, the experimental data, and the design and operation experience, the virtual design (VD) technique is used to investigate the accelerator design. Comparing with conventional methods, VD presents an integrated design environment in which the design, manufacture, assembly, operation and maintenance could be discussed before the machine being built. Because this is a complete development process implemented in computer, innovative idea can be adopted with zero risk. Thus the limitation of the conventional accelerator design method can be conquered. This is a way to get originate design idea with low expense, which will obviously help to improve the accelerator design and manufacture ability to meet the need of development of China. This is also a way that fits the situation of China.

把虚拟设计技术引入低能粒子加速器的设计研究，在已有软件的基础上，完善功能，实现可视化，建立一个完整的加速器虚拟设计环境，从整机角度研究加速器的设计、安装、调试、运行和误差分析，实现整机优化，从而以较低的投入实现创新设计。这是继数值方法引入加速器设计后的第二次突破，将使国内技术达到国际领先水平，为国民经济的发展做出贡献。.
