An embodiment of the present invention includes the use of a single connection to measure the resonance frequency of main cells or side cells of a resonant structure, such as a linear accelerator cavity structure. Only one antenna is require to perform both the tasks of exciting a cavity structure a ...
A system according to some embodiments may include a treatment head to emit treatment radiation, a gantry coupled to the treatment head, an x-ray tube to emit imaging radiation, an imaging device to acquire an image based on the imaging radiation, and a C-arm coupled to the x-ray tube, the imaging d ...
A linear accelerator having cast dielectric composite layers integrally formed with conductor electrodes in a solventless fabrication process, with the cast dielectric composite preferably having a nanoparticle filler in an organic polymer such as a thermosetting resin. By incorporating this cast di ...
A close-coupled rf power system provides high peak rf power for a linear accelerator, or "linac", and other charged particle systems. The linac operates in a vacuum housing. Low level rf power is coupled inside of the vacuum housing by a conventional rf feedthrough connector. An input resonator cavi ...
A high-gradient linear accelerator comprises a solid-state stack in a vacuum of five sets of disc-shaped Blumlein modules each having a center hole through which particles are sequentially accelerated. Each Blumlein module is a sandwich of two outer conductive plates that bracket an inner conductive ...
An x-ray system for treatment cancer by delivering x-ray radiation directly to a desired region of tissue comprising an x-ray source with directed narrow space distribution of x-rays (linear accelerator), conditioning optics which direct and monochromotize x-ray radiation, an implantable needle with ...
A system for generating tunable pulsed monochromatic X-rays comprises a tabletop terawatt laser delivering 10 Joules of energy in 10 ps at a wavelength of 1.1 microns. The light beam from the laser is counter-propagated against an electron beam produced by a linear accelerator. X-ray photons are gen ...
An electromagnetically propelled space transportation system is provided for transporting passengers and/or freight between the Earth's surface and orbiting spaceports via reusable spaceplanes. Each spaceplane is equipped with a plurality of superconducting propulsion coils extending along its fusel ...
The accelerating structure comprises a resonant cavity within which are placed at least two longitudinal conducting supports. One end of each support is electrically connected to the cavity in such a manner as to be in quarter-wave resonance and in opposite phase. Drift tubes are electrically connec ...
In a clinical linear accelerator system for delivering charged particles for medical applications, a series of monolithic cavity-defining members is connected to form a succession of accelerating cavities, with temperature regulation being achieved by aligning internal cooling passageways through th ...
