论文摘要
本文介绍了用于循环加速器的束内反馈系统的历史和演变。这项亲身投资由John D. Fox（Slac/Stanford Un。）在京都举行的IPAC2010上提出。 Pro-Posal的想法是构建一种灵活而强大的工具，以减轻对储存环中质子（和Poten-tim-tim-Tositron）梁的寄生电子云的影响。作为一个新的雄心勃勃的项目，财务问题非常重要。美国LHC加速器研究计划（LARP）和其他机构资助来源保证了在CERN的SPS环中实施反馈的设计。在这里，在LIU（LHC注射器升级）程序的框架中安装和测试了堆放反馈系统TEM。在LARP资金结束后，继续在受电子云效果影响的Lepton存储环中实现系统，可能是继续进行研发活动的新相互作用的机会。为了实现这一目标，可以在意大利Frascati的Dafne的正电子环中进行可能的前物。该提案的可行性在以下各节中进行评估。如果经过实验的批准，则实际上可以将该项目插入DAFNE-TF（DAFNE测试设施）计划中，该计划在随后的3 - 5年后在2020年之后被前景插入。
This paper presents history and evolution of the intra-bunch feedback system for circular accelerators. This pro-ject has been presented by John D. Fox (SLAC/Stanford Un.) at the IPAC2010 held in Kyoto. The idea of the pro-posal is to build a flexible and powerful instrument to mit-igate the parasitic e-cloud effects on the proton (and poten-tially positron) beams in storage rings. Being a new and ambitious project, the financial issues have been quite im-portant. US LHC Accelerator Research Program (LARP) and other institution funding sources have assured the de-velopment of the design for implementing the feedback in the SPS ring at CERN. Here the intra-bunch feedback sys-tem has been installed and tested in the frame of the LIU (LHC Injector Upgrade) program. After the end of the LARP funding, a possible new inter-esting chance to continue the R&D activity, could be by implementing the system in a lepton storage ring affected by e-cloud effects. For achieving this goal, a possible ex-periment could be carried out in the positron ring of DAFNE at Frascati, Italy. The feasibility of the proposal is evaluated in the following sections. In case of approval of the experiment, indeed the project could be inserted in the DAFNE-TF (DAFNE Test Facility) program that is fore-seen after the 2020 for the following 3-5 years.
