MOOTH1 Overview of High Energy e+e− Factories ion, dynamic-aperture, sextupole, radiation 1

  Designs of e+e− colliders from the Z-pole and above are introduced. Two projects, CEPC and FCC-ee, are discussed. If we compare their schemes, a partial double ring (CEPC) and a full double ring (FCC-ee), find several important differences that affect the performance. On the other hand, there are a number of similarities in both designs, such as the crab-waist scheme, crossing angle, optimization of the dynamic aperture, etc.

MOOTH3 Overview on Low Energy Collider ion, luminosity, factory, operation 9
 
  • Q. Qin
    IHEP, Bejing, People's Republic of China
  
  Electron positron colliders cover from low energy machine like Phi factory to very high energy one, Higgs factory, which is still in the way on developing. In this talk, several low energy colliders, DAΦNE as a Phi factory, BEPCII and VEPP-4M as tau-charm factories, and the proposed super charm-tau factories, will be reviewed. The performance and future plans are discussed.

Designs for future high-energy circular electron-positron colliders are based on both established and novel concepts. An appropriate design will allow these facilities to serve not only as ‘‘Higgs factories'', but also as Z, W and top factories, and, in addition, to become a possible first step to a higher-energy hadron collider.

  VEPP-2000 e+e− collider at Budker Institute of Nuclear Physics was commissioned in 2009 and collected data during three runs in whole designed energy range of 160-1000 MeV per beam. The Round Colliding Beams concept was implemented at VEPP-2000 to get a significant enhancement in beam-beam limit. The beam-beam parameter value as high as 0.12 per IP was achieved at intermediate energy. To obtain more intensive beams and achieve target luminosity at top energies the injection chain upgrade was done during 2013-2016. Presently VEPP-2000 is recommissioned and ready to start data taking.

WET3AH3 Extraction Line and Beam Dump for the Future Electron Positron Circular Collider ion, kicker, extraction, electron 188

  The conceptual design of an extraction line and beam dump for the future electron positron circular collider is presented. The proposed extraction line, consisting of abort kicker system, spoilers and beam diagnostics apparatus transports the electron and positron beams to the main beam dumps. The beam must be spread over a large surface in order not to damage the beam dump and the window, which separates the ring from the dump. The extraction line redistributes bunches at different locations on the face of beam dump. Monte Carlo simulations using FLUKA have been performed to estimate the distribution of energy deposition on the window and beam dump to find the optimal absorber and its dimensions.

THS1H5 Summary Beam-beam Session, eeFACT2016 Workshop ion, simulation, beam-beam-effects, resonance 203
 
  • A. Chao

  There are two talks in the beam-beam session. But beam-beam is an issue that permeates in several other sessions. So in this summary I have taken the liberty to include some materials extracted also from other sessions.

  Summary of Injector and Beam Injection: This summary covers the Injection and Sources Session of the e+e- Factories Workshop 2016, which had six presentations. Here we discuss the goals for top-up injection for a collider and their sources and then covers the highlights, discussion topics, and future plans for each presentation.
