Abstract :
Booster synchrotrons, such as the SSC Low Energy Booster, typically require a megavolt RF system which must tune about 25%. The cavity proposed here is longitudinally symmetric with the gaps separated by 140° in proton phase. The two perpendicularly biased ferrite tuners are directly connected to the center conductor and are located on either side of the cavity. The power tube is capacitively coupled to the midpoint of the drift tube. The cavity is designed to provide an energy gain of 1.88×90 keV. The tuner features ferrite toroid which are bonded with epoxy to water cooled copper surfaces. The cavity walls are slotted so that a significant fraction of the ferrite can be tuned by high frequency components of the bias field
