A charged particle beam generator, a charged particle irradiation system, a method for operating the charged particle beam generator and a method for operating the charged particle irradiation system, which allow a charged particle beam to be injected into a circular accelerator 200 at an arbitrary timing and can reduce an irradiation time and a time for a therapy, are provided while maintaining the lower limit of an operation cycle of a linear accelerator 111. An accelerator control device 210 controls an operation of a synchrotron 200 on the basis of a beam extraction request signal transmitted from a beam utilization system control device. A control device 210 generates a timing signal notifying the linear accelerator 111 of an injection timing of a next operation cycle of the synchrotron 200 after completion of an extraction process performed by the synchrotron 200, changes an operation timing of the linear accelerator 111 so that the operation timing of the linear accelerator 111 matches the injection timing.

| A charged particle beam transport system and method for linear accelerators includes a lens stack having two electrodes serially arranged along an acceleration axis between a charged particle source, and a linear accelerator. After producing and extracting a bunch of charged particles (i.e. particle beam) from the particle source, a voltage difference between the two electrodes is ramped in time to longitudinally compress the particle beam to be shorter than the pulsewidth of acceleration pulses produced in the accelerator. Additional electrodes may be provided in the lens stack for performing transverse focusing of the charged particle bunch and controlling a final beam spot size independent of the current and energy of the particle beam. In a traveling wave accelerator embodiment having a plurality of independently switchable pulse-forming lines, beam transport can also be controlled by triggering multiple adjacent lines simultaneously so that the physical size of the accelerating electric field is longer than the charged particle bunch, as well as by controlling trigger timing of the pulse-forming lines to perform alternating phase focusing. | ||||||

| The ion acceleration system or complex (T) for medical and/or other applications is composed in essence by an ion source (1), a pre-accelerator (3) and one or more linear accelerators or linacs (6, 8, 10, 13), at least one of which is mounted on a rotating mechanical gantry-like structure (17). Said isocentrical gantry (17) is equipped with a beam delivery system, which can be either 'active' or 'passive', for medical and/or other applications. The ion source (1) and the pre-accelerator (3) can be either installed on the floor, which is connected with the gantry basement, or mounted, fully or partially, on the rotating mechanical structure (17). The output beam can vary in energy and intensity pulse-by-pulse by adjusting the radio-frequency field in the accelerating modules of the linac(s) and the beam parameters at the input of the linear accelerators. | ||||||

| A high-current, high-gradient, high-efficiency, multi-stage cavity cyclotron resonance accelerator (MCCRA) provides energy gains of over 50MeV/stage, at an acceleration gradient that exceeds 20MeV/m, in room temperature cavities. The multi-stage cavity cyclotron resonance accelerator includes a charged particle source, a plurality of end-to-end rotating mode room-temperature cavities, and provides a substantially uniform magnetic field that threads through the cavities. Specifically, the MCCRA is provided with a constant magnetic field sufficient to produce a cyclotron frequency a little higher than the RF of the accelerating electric field. A plurality of input feeds, each of which respectively coupled to a cavity, are also provided. According to an embodiment of the invention, the beam from the first cavity passes through a cutoff drift tube and is accelerated further with a cavity supporting a still lower radio-frequency electric field. This embodiment yields as several-milliampere one-gigavolt proton beam efficiently. The single cavity transfers about 70 % of the radio-frequency energy to the beam. A multiple-cavity accelerator using a constant or slightly decreasing static magnetic field along its length and using cutoff drift tubes between the cavities operating at progressively lower frequencies, each somewhat lower than the local relativistic cyclotron frequency of the beam in that cavity, provides an extremely-efficient, compact, continuously-operating, medium-energy accelerator. In another embodiment of the invention, the progressively lower frequencies are selected to decrease in substantially equal increments corresponding to a difference frequency. The charged particles are emitted in pulses in correspondence with the difference frequency. | ||||||
