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素方法（TDBEM）的粒子加速器唤醒场分析的专用计算机系统。TDBEM为我们提供了对尾流场进行自洽分析和在下一代高能粒子加速器中的自洽分析的有吸引力的可能性，尤其是用于分析在乘坐型固定型固定型固定型固定器层的同步分析。然而，众所周知，TDBEM要求我们非常庞大的存储记忆和繁重的计算成本，这些问题使我们无法实际应用TDBEM来唤醒现场分析。在该项目的期限，对尾流场分析的专用计算机系统进行调查如下所示，（1）将TDBEM方案分类为TDBEM的分类（1）在两部分中进行了分类，该片段的架构（2）在“难题”中进行了（2），该范围（2）在2份中进行了处理（2），并在2份中进行了处理（2）。 TDBEM方案（3）使用VHDL使用VHDL进行的专用C…更多计算机数字电路的详细设计。（4）确认通过VHDL逻辑模拟对小型模型的专用计算机的正常操作，证实TDBEM专用的计算机系统可以通过上述功能来实现以上的努力，例如已准备好的fpga。对于TDBEM方案中的大型存储内存问题，也是从软件观点完成的。将常规（隐式）TDBEM方案修改为显式方案，并将所谓的“窗口选项”技术应用于TDBEM。为了进行这种修改，可以通过TDBEM方案进行实用粒子加速器腔模型（例如Tesla 9细胞结构（DESY））的唤醒场分析。通过将专用的计算机系统和修改的TDBEM软件结合并将计算机系统应用于真实的BUNCH压缩机中的粒子动力学来实现高性能计算机系统的未来工作。较少的
