Abstract

This paper presents history and evolution of the intra-bunch feedback system for circular accelerators. This project has been presented by John D. Fox (SLAC/Stanford Un.) at the IPAC2010 held in Kyoto. The idea of the proposal is to build a flexible and powerful instrument to mitigate the parasitic e-cloud effects on the proton (and potentially positron) beams in storage rings. Being a new and ambitious project, the financial issues have been quite important. US LHC Accelerator Research Program (LARP) and other institution funding sources have assured the development of the design for implementing the feedback in the SPS ring at CERN. Here the intra-bunch feedback system 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 interesting 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 experiment 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 foreseen after the 2020 for the following 3-5 years.
