  • Patent number: 12010788
    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.

  • Publication number: 20230284368
    Abstract: Embodiments of systems, devices, and methods relate to exclusion of ion beam paths on the target surface to optimize neutron beam performance. A particle beam is directed along an axis so that the particle beam is incident on a target positioned on the particle beam axis. The target has a scannable surface extending over an area substantially orthogonal to the axis. The particle beam is scanned across the scannable surface of the target along a first path having a first flux. The particle beam, having a second flux, is scanned across the scannable surface of the target along a second path that is within an exclusion area of the target.

  • Publication number: 20230249002
    Abstract: Embodiments of systems, devices, and methods relate to a beam system. An example beam system includes a charged particle source configured to generate a beam of charged particles, a pre-accelerator system configured to accelerate the beam, and an accelerator configured to accelerate the beam from the pre-accelerator system. The pre-accelerator system can cause the beam to converge as it is propagated from the source to an input aperture of the accelerator. The pre-accelerator system can further reduce or eliminate source disturbance or damage caused by backflow traveling from the accelerator toward the source.

  • Publication number: 20210166832
    Abstract: Embodiments of systems, devices, and methods relate to fast beam position monitoring for detecting beam misalignment in a beam line. In an example, a fast beam position monitor includes a plurality of electrodes extending into an interior of a component of a beam line. The fast beam position monitor is configured to detect a position of a beam passing through the component of the beam line based on beam halo current. Embodiments of systems, devices, and methods further relate to noninvasively monitoring parameters of beams advancing along a beam line. In examples, gas is puffed into a pumping chamber along a beam line. One or more beam parameters are measured from fluorescence resulting from collisions of energetic beam particulates of a beam advancing through the beam line.

  • Patent number: 8648532
    Abstract: A High Intensity Discharge (HID) lamp includes a discharge chamber disposed within an anti-oxidation envelope and protected by a shroud. The shroud encloses the anti-oxidation envelope and thereby the discharge chamber to prevent the emission of fragments in the event that the discharge chamber fails. The shroud is positioned around the anti-oxidation envelope by a compressed spring at one end of the envelope tensioned against a collar attaching the other end of the envelope to a base of the lamp.
