Abstract: A hadron therapy system that provides 3D scanning and rapid delivery of a high dose. Such systems can include a hadron source and accelerator with an RF energy modulator and an RF deflector that operate in combination to provide 3D scanning of a targeted tissue. The systems can include a permanent magnet quadrupole for magnification of the beam. The systems can include high energy hadron sources that utilize a multi-cell, multi-klystron design that achieves scanning of high energy hadron beams, for example a fixed energy of 200 MeV protons. Such systems can provide full irradiation of a liter scale tumor within one second or less.

Abstract: A microwave circuit for a linear accelerator has multiple metallic cell sections, a pair of distribution waveguide manifolds, and a sequence of feed arms connecting the manifolds to the cell sections. The distribution waveguide manifolds are connected to the cell sections so that alternating pairs of cell sections are connected to opposite distribution waveguide manifolds. The distribution waveguide manifolds have concave modifications of their walls opposite the feed arms, and the feed arms have portions of two distinct widths. In some embodiments, the distribution waveguide manifolds are connected to the cell sections by two different types of junctions adapted to allow two frequency operation.
