Bunch-by-bunch position measurement and analysis at PLS-II.
A bunch-by-bunch measurement system has been developed at Pohang Light Source II. The system consists of a four-channel button pick-up, 20 GHz sampling oscilloscope and an 800 MHz low-pass digital filter. Upon measuring a bunch-by-bunch spatio-temporal beam motion matrix over many turns, singular-value decomposition analysis is used to reveal the dominant coupled-bunch modes. The system can dia...
متن کاملBunch-by-bunch Feedback and Diagnostics at Bessy Ii
At the light source BESSY II new digital bunch-bybunch feedback systems [1] have been put into operation in January 2013, replacing the existing analog as well as the obsolete digital systems. From the first days of operation the new system successfully suppresses transverse and longitudinal beam instabilities in wide range of machine parameters. The system offers also many new diagnostics oppo...
متن کاملBunch-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 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 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...
