A new engineering design of ferrite tuners for rapid-cycling-booster rf cavities is proposed. The basic concept is to divide a perpendicularly biased ferrite tuner into two (or more) successive or parallel sections which are magnetically biased in opposite directions. This approach aims at several improvements with respect to existing designs: (a) reduction of magnet weight (b), lower eddy currents, (c) reduction (or cancellation) of magnetic fields on beam axis, and (d) possibility of increasing the tuner breakdown voltage by stepwise widening of airgaps between ferrite layers of successive tuner sections. Some details are illustrated for stripline tuners, especially for the Low-Energy- and Medium-Energy-Boosters (LEB and MEB) in the Supercollider injector scenario.
