To achieve a very high electron beam current for bunched beam cooling in the future high luminosity upgrade, we adopt a circulator ring to reuse the electron bunches. The electron bunches will recirculate for 25 turns, thus the current in the ERL can be reduced by a factor of 25. An ultra-fast kicker is required for this circulator ring, with pulse width less than 2.1 ns and high repetition frequency. JLab started an LDRD proposal to develop such a kicker. Our approach is to generate a series harmonic mode with RF resonant cavities, thus every 25th bunch will be kicked while all the other bunches un-kicked. Here we present a design of a simplified prototype with every 10th bunch kicked, using 4 cavities to generate 10 harmonic modes. Cavity structure is optimized to get the highest shunt impedance, thus the total power dissipated on 4 cavities for copper material is only 87.72 W, two to three orders of magnitude lower than a strip-line kicker.
