Abstract: Embodiments of systems, devices, and methods relate to initiating beam transport for an accelerator system. An example method includes increasing a bias voltage of one or more electrodes of the accelerator system to a first voltage level and extracting a charged particle beam from a beam source such that the beam is transported through the accelerator system. The beam has a beam current that results in a first transient voltage drop within a threshold. The method further includes increasing the beam current at a rate that results in one or more subsequent transient voltage drops within the threshold until the accelerator system has reached nominal conditions. Another example method includes biasing one or more electrodes of an accelerator system and selectively extracting, according to a duty cycle function, a charged particle beam from a beam source such that the charged particle beam is transported through the accelerator system.

Abstract: A linear accelerator head for use in a medical radiation therapy system can include a housing, an electron generator configured to emit electrons along a beam path, and a microwave generation assembly. The linear accelerator head may include a waveguide that is configured to contain a standing or travelling microwave. The waveguide can include a plurality of cells that are disposed adjacent one another, wherein each of the plurality of cells may define an aperture configured to receive electrons therethrough. The linear accelerator head can further include a converter and a primary collimator.

Abstract: A continuous wave (CW) electron accelerator for the treatment of industrial streams including an electron beam source, a modified high efficiency slot coupled cavity, at least one focusing magnet positioned surrounding the accelerator to contain the beam in the accelerator, an efficient radio frequency power supply means for supplying power of a radio frequency to the cavity to induce a TM01 accelerating mode in the cavity, an electron beam spreader or raster, a fixed magnet array or two-dimensional scanning magnet for deflecting the accelerated beam into a desired shape, and an exit window for extracting the deflected electron beam. The accelerator includes a graded-beta cavity to enable use with a low-power pulsed electron source. The accelerator benefits from a low wall-power loss accelerating cavity that is energized with efficient RF sources, enabling it to be operated in continuous wave mode.

Abstract: A linear accelerator system comprising a source arranged to produce a pulsed beam of charged particles, a linear accelerator string arranged to accelerate the pulsed beam up to a predetermined range of energies, and a pre-acceleration stage interposed between the source and the linear accelerator string and arranged to accelerate the pulsed beam up to an energy suitable for beam insertion into the linear accelerator string and perform bunching of the pulsed beam. An average current detector is arranged to measure an average current in the pulsed beam, the average current detector comprising at least one non-interceptive sensor placed at an input side of the linear accelerator string, downstream of the pre-acceleration stage, the sensor being responsive to the pulsed beam passing thereby.

Abstract: A system (12) is proposed for the acceleration of ions to treat Atrial Fibrillation (AF), arteriovenous malformations (AVMS) and focal epileptic lesions; this system (12) includes a pulsed ion source (1), a pre-accelerator (3) and one or more linear accelerators or linacs (5, 6, 7) operating at frequencies above 1 GHz with a repetition rate between 1 Hz and 500 Hz. The particle beam coming out of the complex (12) can vary (i) in intensity, (ii) in deposition depth and (iii) transversally with respect to the central beam direction. The possibility of adjusting in a few milliseconds and in three orthogonal directions, the location of each energy deposition in the body of the patient makes that system of accelerators (12) perfectly suited to irradiation of a beating heart.
