To enable avoiding interference between a path of a separated charged particle beam and an electromagnet as well as providing a sufficient separation distance between: a path of a separated charged particle beam; and a path of a charged particle beam traveling in a main region. A quadrupole electromagnet includes: an iron core provided with a beam passing gap for travel of an output beam that is a separated charged particle beam, in addition to a main region for travel of a circulating beam that is a charged particle beam; excitation coils, and each wound around the iron core; a main vacuum duct, provided in a main region of the iron core, inside which the circulating beam travels; and a sub-vacuum duct, provided in the beam passing gap of the iron core, inside which the output beam travels.

A gantry-less particle therapy system is provided. Charged particles are extracted from an ion source and accelerated in a beam transport system having an annular portion extending in a first plane and that circumscribes a volume, an arcuate portion extending in a second plane, and a transition portion that connects the annular portion and the arcuate portion. The arcuate portion terminates at a beam nozzle extending radially inward from the annular portion to deliver an ion beam to a treatment area contained in the volume circumscribed by the annular portion.

Embodiments of the present invention provide a compact gantry designed to provide particle therapy using a particle beam. A gantry for providing the particle therapy comprises a first dipole magnet operable to bend a particle beam received from a cyclotron by a first degree amount. The gantry further comprises a plurality of quadrupole magnets configured to condition the beam asymmetrically to produce an asymmetric beam, wherein a configuration of the quadrupole magnets is determined using a dispersion function of a second dipole magnet. Further, the second dipole magnet is operable to receive the asymmetric beam and bend the asymmetric beam by a second degree amount, and wherein the second dipole magnet disperses the asymmetric beam to produce a symmetric beam shape at a treatment iscoenter or at any other reference point.

A filter is provided. The filter includes a mixed layer. The mixed layer includes aluminum, magnesium fluoride, and lithium fluoride. The mixed layer is composed of 1 part by volume of magnesium fluoride, 0.25 to 1 parts by volume of aluminum, and 0.003 to 0.02 parts by volume of lithium fluoride.

An ion implantation system has a source that generates ions from a beam species to form an ion beam, and a mass analyzer mass analyzes the ion beam. An accelerator receives the ion beam having ions at a first charge state and exits the ion beam having ions at a second positive charge state. The accelerator has a charge stripper, a gas source, and a plurality of accelerator stages. The charge stripper converts the ions from the first charge state to the second charge state. The gas source provides a high molecular weight gas, such as hexafluoride, to the charge stripper, and the plurality of accelerator stages respectively accelerate the ions. An end station supports a workpiece to be implanted with ions at the second charge state.

An example particle therapy system may include: a synchrocyclotron to produce a particle beam; a scanner to move the particle beam in one or more dimensions relative to an irradiation target; and an energy degrader that is between the scanner and the irradiation target. The energy degrader may include multiple plates that are movable relative to a path of the particle beam, with the multiple plates each being controllable to move while in the path of the particle beam and during movement of the particle beam. An aperture may be between the energy degrader and the irradiation target. The aperture being may be to trim the particle beam prior to the particle beam reaching the irradiation target.

Described are devices, systems, and methods for modulating the spectral energy distribution produced by an x-ray source via control of the energy of the x-ray-generating electron beam, e.g., for energy-modulated radiation therapy or other purposes. In some embodiments, such energy modulation is achieved by an add-on device to a linear accelerator. Also disclosed are computational methods and computer program products for planning energy-modulated therapy.

A volume interrogation system can use an accelerated beam of charged particles to interrogate objects using charged-particle attenuation and scattering tomography to screen items such as portable electronic devices, packages, baggage, industrial products, or food products for the presence of materials of interest inside. The exemplary systems and methods in this patent document can be employed in checkpoint applications to scan items. Such checkpoint applications can include border crossings, mass transit terminals (subways, buses, railways, ferries, etc.), and government and private-sector facilities.
