Abstract
Q-switching operation of the storage ring FEL provides high peak power and is therefore very attractive to application experiments. On the UVSOR, the Q-switching is performed by modulation of an RF frequency. Collective synchrotron oscillation of the electron bunch is excited in the actual operation. However, it is found that damping time of the oscillation is 100 times faster than the one expected from synchrotron radiation, so the influence of the collective oscillation on the lasing is relatively small. Analysis reveals that the phenomenon is explained with Robinson damping.
