This proposal recommends the support of an outstanding opportunity for inward investment from the US to the UK through collaboration between Tech-X and the Cockcroft Institute to provide massively parallel electromagnetic computational solutions for 'high tech' UK businesses. Success will give UK industry the edge in the development of a whole range of high power RF and microwave systems. The inward investment will strengthen UK science by the provision of a world leading capability for the analysis of other problems in electromagnetics including laser plasma interactions. Through collaboration with NW-GRID and the proposed Hartree Centre the Daresbury Science and Innovation Campus (DSIC) will be strengthened as a centre of excellence in high power computing. The engineering of particle accelerators and microwave tubes depends heavily on the use of simulation software for analysis of the electromagnetic fields in cavity resonators, slow-wave structures and related components. Powerful computer codes are routinely used for this purpose. Many of these codes incorporate Particle in Cell (PIC) solvers which allow the interaction between charged particles and radio-frequency electromagnetic fields to be studied. However, it is found that it is frequently impossible to model real problems because of the limited capacity of even powerful workstations. Problems which cannot be modeled using these codes include the following important cases: Non-linear performance of microwave tubes in the time domain; Radio-frequency vacuum discharges; and Collimator wakefields. For problems such as these a PIC code which is designed to be run on massively parallel (grid) computers is required. The project will employ the Tech-X code VORPAL which has been designed to run on massively parallel computing systems. This code has already been used to model problems in plasma physics and particle accelerators including accelerating structures, plasma wakefield accelerators and radio-frequency discharges in superconducting cavities. This project will use NW-GRID to model experimental data on the topics mentioned above generated in previous funded projects. The work will be carried out jointly by the Cockcroft Institute for Accelerator Science and Technology, though the High Power RF Engineering group at Lancaster University, and staff employed by a newly created UK subsidiary of Tech-X based on the Daresbury Science and Innovation Campus. The project will facilitiate the establishment of Tech-X UK and the associated inward investment on Daresbury Science and Innovation Campus by the parent company. It will assist Tech-X with the development of its products in ways that will be valuable to UK and European customers. In particular, the Cockcroft scientists bring valuable knowledge about critical modeling needs for RF component design and about the process of RF component design. The project will also enhance the ability of the Cockcroft Institute to use state-of-the art computational methods in its research.

该提案建议通过Tech-X和Cockcroft Institute之间的合作，支持从美国到英国的外来投资的绝佳机会，为英国的高科技企业提供大规模并行的电磁计算解决方案。成功将使英国工业在开发一整套高功率射频和微波系统方面具有优势。这笔外来投资将为包括激光等离子体相互作用在内的电磁学其他问题的分析提供世界领先的能力，从而加强英国的科学。通过与NW-GRID和拟议的哈特里中心合作，达累斯伯里科学和创新园区将得到加强，成为高功率计算领域的卓越中心。粒子加速器和微波管的工程在很大程度上依赖于使用仿真软件来分析腔谐振器、慢波结构和相关部件中的电磁场。功能强大的计算机代码通常用于这一目的。其中许多代码包含了粒子在单元(PIC)解算器，它允许研究带电粒子和射频电磁场之间的相互作用。然而，人们发现，由于即使是功能强大的工作站的能力有限，也经常不可能对实际问题进行建模。不能用这些程序模拟的问题包括以下重要情况：微波管在时间域中的非线性性能；射频真空放电；准直器尾流场。对于这样的问题，需要设计成在大规模并行(网格)计算机上运行的PIC代码。该项目将采用Tech-X代码VOPAL，该代码被设计为在大规模并行计算系统上运行。该程序已被用于模拟等离子体物理和粒子加速器中的问题，包括加速结构、等离子体尾迹加速器和超导腔中的射频放电。该项目将使用NW-GRID对以前资助的项目中产生的上述主题的实验数据进行建模。这项工作将由Cockcroft加速器科学与技术研究所、兰开斯特大学的高功率射频工程小组和Tech-X在达累斯伯里科学与创新园区新成立的英国子公司雇用的员工共同开展。该项目将促进Tech-X UK的建立，以及母公司在达累斯伯里科学和创新园区的相关外来投资。它将帮助Tech-X以对英国和欧洲客户有价值的方式开发其产品。特别是，Cockcroft的科学家带来了关于射频组件设计的关键建模需求和射频组件设计流程的宝贵知识。该项目还将增强考克罗夫特研究所在其研究中使用最先进的计算方法的能力。
