The schemes for full-energy top-up injection into an e+e− collider will be discussed emphasizing technical issues to be accommodated. The issues include energy stability, energy spread control, transverse emittance reduction, transverse position and angle stability, collimation, background control in the detector, detector blanking of event triggers, and bunch filling strategies. Strategies and observations from PEP-II and KEKB will be included.

Top-up injection has become standard mode of operation for most third generation light sources, and has also been suc- cesfully applied in electron-positron circular colliders like KEKB and PEP-II. For next generation ultra-low emittance storage rings approaching the diffraction limit of X-rays, take the High Energy Photon Source (HEPS) for example, top-up injection is a basic requirement but non-trivial to im- plement. The very small dynamic aperture is insufficient for traditional off-axis injection scheme, instead, a novel on-axis injection scheme was recently proposed for HEPS, based on RF gymnastics of a double-frequency RF system. This paper will describe the physical mechanism of this scheme, related RF issues, and the implications for top-up injection.

TUT3BH3 Luminosity Tuning at KEKB ion, luminosity, operation, coupling 147
 
  • Y. Funakoshi
    KEK, Ibaraki, Japan
  
  KEKB achieved the world's highest luminosity. One of the key issues for the high luminosity at KEKB was a luminosity tuning which was done almost every time even during the physics run to suppress the beam-beam blowup. In this talk, those experiences are summarized. Some experiences of the luminosity tuning at TRISTAN will also mentioned.

  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.
