Measurement of Damping Time and Frequency of Coherent Synchrotron Oscillation in PF Storage Ring

摘要

The damping time and the frequency of the coherent synchrotron oscillation in the PF storage ring were studied. A weak beam phase oscillation was induced by feeding an external perturbation to an acceleration phase control circuit, and the beam oscillation was measured with a signal from a beam position monitor. Observed damping was much stronger than that of the calculated value using the Robinson damping mechanism. (Atomindex citation 16:046097)
