Abstract :
Pickup and kicker electrodes that function in the 4-8 GHz frequency range were designed for bunched beam cooling applications in the Fermilab Tevatron. The electrodes are planar and are fabricated with photolithographic techniques on woven Teflon board. The electrodes have a variable transverse aperture ranging from 0.75 to 4 in to accommodate the changing beam size in the Tevatron during acceleration. To accommodate the plunging action of the electrodes, a unique flexible microwave transition piece was incorporated into the design.<>
