Abstract :
A significant reduction in 60 Hz beam motion has been achieved in the UV storage ring. From the wide band harmonic beam motion signal, 60 Hz signal is extracted by tuned bandpass filter. This signal is processed by the phase and amplitude adjustment circuits and then, it is fed into the harmonic orbit generation circuits. Several harmonics, near the tune, were cancelled by employing one circuit for each harmonic. The design and description of this experiment is given in this paper. The results showing reduction in beam motion at 60 Hz are also provided
