Bunch-by-Bunch Feedback for PEP II*
The proposed PEP II B factory at SLAC requires a feedback to damp out longitudinal synchrotron oscillations. A time domain, downsampled, bunch-by-bunch feedback system in which each bunch is treated as an oscillator being driven by disturbances from other bunches is presented as we review the evolution of the system design. Results from a synchrotron oscillation damping experiment conducted at ...
متن کاملSuperb Bunch - by - Bunch Feedback R & D *
The SuperB project has the goal to build in Italy, in the Frascati or Tor Vergata area, an asymmetric e+/eSuper Flavor Factory to achieve a peak luminosity > 10**36 cm-2 s-1. The SuperB design is based on collisions with extremely low vertical emittance beams and high beam currents. A source of emittance growth comes from the bunch by bunch feedback systems producing high power correction signa...
متن کاملCommissioning of the Digital Transverse Bunch-by-bunch Feedback System for the TLS
Multi-bunch instabilities degrade beam quality through increased beam emittance, energy spread and even beam loss. Feedback systems are used to suppress multi-bunch instabilities associated with the resistive wall of the beam ducts, cavity-like structures, and trapped ions. A new digital transverse bunch-by-bunch feedback system has recently been commissioned at the Taiwan Light Source, and has...
متن کاملDo-wnsampled Bunch-by-Bunch Feedback for PEP II*
_~ Figure 1: Conceptual diagram of bunch-by-bunch feedback. The phase-of each bunch is detected and a feedback signal particular to that bunch is produced by the filter and is applied via the kicker. _~ The phase is.. dejected, filtered, and the feedback correction signal is applied by the kicker. Since we are damping energy oscillations using measurements of phase, the required feedback signal...
متن کاملBunch by Bunch Feedback Systems for the Kekb Rings
Transverse bunch-by-bunch feedback systems for damping coupled-bunch instabilities in the KEKB rings have been working since the early stage of the commissioning of the rings. Stabilization of the beams with the system have been successful, permitting tests of higher beam currents and various filling patterns. The performance of these systems has been demonstrated under the normal physics run p...
