摘要： A remote diagnostic monitoring of operating states for physical components of a particle accelerator system includes generating, by at least one processor, a component hierarchy corresponding to a physical arrangement of one or more physical components of a particle emitting system and including corresponding operating indicators of operating states of the physical components, identifying, by the at least one processor, a faulted physical component among the physical components, identifying, by the at least one processor, one or more fault path components among the physical components, the fault path components corresponding to a portion of the physical arrangement associated with the faulted physical component, and modifying, by the at least one processor, the operating indicators of the fault path components to fault state indicators.

摘要： 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.

摘要： A drift tube may include a middle portion, arranged as a hollow cylinder, and coupled to receive an RF voltage signal. The drift tube may include a first end portion, adjacent to and electrically connected to the middle portion. The middle portion and the first end portion may define a central opening to conduct an ion beam therethrough, along a direction of beam propagation. The first end portion may include a first focus assembly, and a second focus assembly, where the first focus assembly and the second focus assembly are movable with respect to one another along the direction of beam propagation, from a first configuration to a second configuration.

摘要： A synchrocyclotron for extracting charged particles accelerated to an extraction energy includes a magnetic unit comprising N valley sectors and N hill sectors, and configured for creating z-component of a main magnetic characterized by a radial tune of the successive orbits. The synchrocyclotron includes a first instability coil unit and a second instability coil unit configured for creating a field bump of amplitude increasing radially. The amplitude of the field bump may be varied to reach the value of the offset amplitude at the average instability onset radius. The offset amplitude may be the minimal amplitude of the field bump at the average instability onset radius required for sufficiently offsetting the center of the orbit of average instability onset radius to generate a resonance instability to extract the beam of charged particle at the average instability onset radius.

摘要： An RF accelerating cavity includes: a housing having an inner peripheral surface in a tubular shape and conductivity at least on a surface; and accelerating cells inside the housing and each made of a dielectric including, at a central part, an opening through which a charged particle passes. The housing includes a cylindrical barrel portion, with end plates at both ends. The accelerating cells are disposed between the end plates. Each accelerating cell includes: a cylindrical barrel portion having a diameter smaller than an inner diameter of the cylindrical barrel portion of the housing; and a circular disk portion provided inside the cylindrical barrel portion to be fixed to the cylindrical barrel portion, and disposed such that a plate surface is orthogonal to the passing axis of a charged particle, and provided with the opening.

摘要： Radioisotope production system includes an electrical field system and a magnetic field system that are configured to direct a particle beam of charged particles along a beam path within an acceleration chamber. The magnetic field system is energized by a drive current to generate a magnetic flux into the acceleration chamber for controlling the particle beam. The radioisotope production system also includes a target system configured to hold a target material and receive the particle beam. The radioisotope production system also includes a monitoring system that is configured to: (a) determine an operating parameter of the radioisotope production system as the particle beam is directed toward the target material and (b) change the drive current, thereby changing the magnetic flux, based on the operating parameter.

摘要： An accelerator 4 includes a circular vacuum container including circular return yokes 5A, 5B. An injection electrode 18 is disposed closer to an inlet of a beam extraction path 20 in the return yoke 5B than a central axis C of the vacuum container. Magnetic poles 7A to 7F are radially disposed from the injection electrode 18 at the periphery of the injection electrode 18 in the return yoke 5B. Recessions 29A to 29F are disposed alternately with the magnetic poles 7A to 7F in the circumferential direction of the return yoke 5B. In the vacuum container, a concentric trajectory region, in which multiple beam turning trajectories centered around the injection electrode 18 are present, is formed, and an eccentric trajectory region, in which multiple beam turning trajectories eccentric from the injection electrode 18 are present, is formed around the region.

摘要： In one embodiment of the invention, a method for irradiating a target is disclosed. A proton beam is generated using a cyclotron. A first information is provided to an energy selection system. An energy level for the protons is selected using an energy selection system based on the first information. The first information comprises a depth of said target. The proton beam is routed from the cyclotron through a beam transfer line to a scanning system. A second information is provided to the scanning system. The second information comprises a pair of transversal coordinates. The proton beam is guided to a location on the target determined by the second information using a magnet structure. The target is irradiated with the protons.
