项目摘要

Dedicated computer system for particle accelerator wake field analysis which are based on time domain boundary element method (TDBEM) are investigated.The TDBEM gives us attractive possibility of self-consistent analysis of wake fields and charged particle motion in the next generation high energy particle accelerators, especially for analysis of coherent synchrotron radiation in bunch compressor section of the Linear Colliders. However, it was known that the TDBEM requires us extremely large storage memory and heavy computation cost, and these matters prevent us from practically applying the TDBEM to wake field analysis.During the term of this project, investigation of the dedicated computer system for the wake fields analysis was done as follows,(1) Making classification of the TDBEM scheme into two parts, process which are done in the hardware and software(2) Consideration on dedicated computer architecture of the hardware part of the TDBEM scheme(3) Detail design of the dedicated c … More omputer digital circuit by using VHDL.(4) Confirmation of the normal operation of the dedicated computer by VHDL logical simulation for small size modelIt was confirmed that the TDBEM dedicated computer system can be realized by the above works if enough amount of hardware parts such as memory, FPGA are prepared.In addition to the consideration on the hardware system for the TDBEM, another efforts for the large storage memory problems in the TDBEM scheme was also done from the software viewpoints. The conventional (implicit) TDBEM scheme was modified to explicit scheme and so-called "window option" technique was applied to the TDBEM. To do this modification, wake fields analysis for practical particle accelerator cavity models such as the TESLA 9 cell structure (DESY) can be done by the TDBEM scheme.It will be future works to achieve high performance computer system by combining the dedicated computer system and the modified TDBEM software, and apply the computer system to particle dynamics in real bunch compressors.

研究了基于时域边界元法（TDBEM）的粒子加速器尾流场分析专用计算机系统。TDBEM为下一代高能粒子加速器的尾流场和带电粒子运动的自洽分析提供了有吸引力的可能性，特别是对直线对撞机束束压缩段相干同步辐射的分析。然而，众所周知，TDBEM需要极大的存储内存和沉重的计算成本，这些问题阻碍了我们将TDBEM实际应用于尾流场分析。本课题对尾流场分析专用计算机系统进行了如下研究：(1)将TDBEM方案分为硬件和软件两部分进行分类；(2)对TDBEM方案硬件部分专用计算机体系结构的思考；(3)利用VHDL对专用计算机数字电路进行了详细设计。(4)通过VHDL对小尺寸模型进行逻辑仿真，证实了TDBEM专用计算机系统的正常运行，如果准备足够数量的存储器、FPGA等硬件部件，则可以通过上述工作实现TDBEM专用计算机系统。除了对TDBEM方案的硬件系统进行考虑外，还从软件的角度对TDBEM方案中存在的大存储空间问题进行了研究。将传统的（隐式）TDBEM格式修改为显式格式，并将“窗口选项”技术应用于TDBEM。为此，可以采用TDBEM方案对特斯拉9细胞结构（DESY）等实际粒子加速器腔模型进行尾流场分析。将专用计算机系统与改进后的TDBEM软件相结合，实现高性能的计算机系统，并将计算机系统应用于实际束束压缩机的粒子动力学，是今后的工作方向。少
