Abstract: A method for compensating the effects of misalignment between deflecting magnetic fields and a linear accelerator in a race track microtron where properly injected and accelerated electrons travel along successive complete orbits numbered in sequence comprising the steps of generating on both sides of the linear accelerator a compensating magnetic field perpendicular to the common plane of the orbits, each field intersecting all complete successive orbits and having a field strength in the regions of the intersections varying stepwise from intersection to intersection, and simultaneously varying the field strength at the intersections while maintaining a linear relationship between the field strength at an intersection and the number of the intersecting complete orbit.

Abstract: An electron accelerator comprising a resonant cavity, an electron source, an RF system, and at least one magnet unit is provided. The resonant cavity further comprises a hollow closed conductor and the electron source is configured to radially inject a beam of electrons into the cavity. The RF system is configured to generate an electric field to accelerate the electrons along radial trajectories. The at least one magnet unit further comprises a deflecting magnet configured to generate a magnetic field that deflects an electron beam emerging out of the resonant cavity along a first radial trajectory and redirects the electron beam into the resonant cavity along a second radial trajectory. The resonant cavity further comprises a first half shell, a second half shell, and a central ring element.

Abstract: A method and electron linac system for production of radioisotopes is provided. The electron linac is an energy recovery linac (ERL) with an electron beam transmitted through a thin bremsstrahlung radiator. Isotopes are produced through bremsstrahlung photon interactions in an isotope production target that is spatially separated from the bremsstrahlung radiator. The electron beam does not pass through the isotope production target. The electron beam energy is recollected and reinjected into the linac accelerating structure. The reduction of material in the beam by removing the isotope production target and making the radiator thin is the essential aspect of the invention because large spreads in energy and transverse scattering angles caused by material in the beam preclude efficient energy recovery. The method described here can reduce the cost of energy to produce a quantity of radioisotope by more than a factor of 3 compared to a non-ERL bremsstrahlung method.

Abstract: A mobile system for electron beam intraoperative radiation therapy uses a race-track microtron placed in a housing playing the role of the vacuum chamber, which is supported by a positioner providing its motion with six degrees of freedom with respect to a patient. The positioner is a part of a mobile mechanical structure which houses an ion pump, a microwave source, waveguide elements, a modulator with a pulse transformer and a cooler. The intraoperative radiation therapy system has a tube-like unit which couples the vacuum chamber with the mobile supporting mechanical structure and provides three functions, namely pumping out of the air from the vacuum chamber, feeding of the race-track microtron accelerating structure with radiofrequency power and rotation of the vacuum chamber with respect to the horizontal axis of the unit.
