Abstract :
A symmetric optical klystron (OK) with an independently adjusted modulator, buncher and radiator has been designed and constructed for a storage ring FEL in NSRL. The designed OK parameters are listed and checked by the 3-dimensional electromagnetic computation code and Hall probe measurements. Special considerations are given for correction factors of OK analysis of a single period buncher and multiperiod undulators induced by 3d magnetic effects. The effect of undulator fill factor on the electron energy is analysed
