Active RF cavity including a plurality of solid state transistors

Abstract

An active RF cavity is defined by a conductive wall in which a plurality of solid state power amplifiers are mounted. The solid state power amplifiers induce an RF current at an inner surface of the wall to form an oscillating electromagnetic (EM) field within the cavity. Preferably, the power amplifiers are in the form of modules that contain a number of RF power chips. The structure operates as both a power combiner and a matching transformer and is powered by a relatively low voltage d.c. source. A high-amplitude field is generated using equipment that is more efficient and much lighter in weight than conventional equipment. Such a cavity may be applied in a drift tube linac, an RF quadrupole linac, a linac having aligned cavities, and in other types of particle accelerators, and as a high power RF amplifier with the EM waves piped out via a waveguide or a coaxial cable.
