  • 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.

  • Patent number: 11615896
    Abstract: Systems and methods are provided that facilitate stability of an FRC plasma in both radial and axial directions and axial position control of an FRC plasma along the symmetry axis of an FRC plasma chamber. The systems and methods exploit an axially unstable equilibria of the FRC plasma to enforce radial stability, while stabilizing or controlling the axial instability. The systems and methods provide feedback control of the FRC plasma axial position independent of the stability properties of the plasma equilibrium by acting on the voltages applied to a set of external coils concentric with the plasma and using a non-linear control technique.

  • Patent number: 11558954
    Abstract: A non-resonance photo-neutralizer for negative ion-based neutral beam injectors. The non-resonance photo-neutralizer utilizes a nonresonant photon accumulation, wherein the path of a photon becomes tangled and trapped in a certain space region, i.e., the photon trap. The trap is preferably formed by two smooth mirror surfaces facing each other with at least one of the mirrors being concave. In its simplest form, the trap is elliptical. A confinement region is a region near a family of normals, which are common to both mirror surfaces. The photons with a sufficiently small angle of deviation from the nearest common normal are confined. Depending on specific conditions, the shape of the mirror surface may be one of spherical, elliptical, cylindrical, or toroidal geometry, or a combination thereof.

  • Patent number: 11363708
    Abstract: A negative ion-based beam injector comprising a negative ion source and an accelerator. The ions produced by the ion source are pre-accelerated before injection into a high energy accelerator by an electrostatic multi-aperture grid pre-accelerator, which is used to extract ion beams from the plasma and accelerate to some fraction of the required beam energy. The beam from the ion source passes through a pair of deflecting magnets, which enable the beam to shift off axis before entering the high energy accelerator. The negative ion-based beam injector can be combined with a neutralizer to produce about a 5 MW neutral beam with energy of about 0.50 to 1.0 MeV. After acceleration to full energy, the beam enters the neutralizer where it is partially converted into a neutral beam. The remaining ion species are separated by a magnet and directed into electrostatic energy converters. The neutral beam passes through a gate valve and enters a plasma chamber.
