Patent number: 10886031Abstract: A combination flux loop and B-dot probe comprising a single mineral insulated cable having an outer sheath of, e.g., stainless steel or the like, and three (3) conductors positioned within the sheath and embedded in a mineral insulator such as, e.g., MgO. One of the conductors forms a flux loop having a single loop and second and third conductors forming a B-dot probe comprises a single wire having a double loop. The combination probe is configured to prevent twisting of the conductors along a curved bend as the combined probe is fashioned into a curved shape. To prevent twisting, the conductors may be formed as ribbon wires having a generally flat, rectangular shaped cross-section and/or the sheath may have a generally oval or rectangular shaped cross-section.Type: GrantFiled: December 27, 2018Date of Patent: January 5, 2021Assignee: TAE TECHNOLOGIES, INC.Inventors: Matthew Thompson, Thomas Roche, Erik Trask, Kurt Knapp

Patent number: 10887976Abstract: 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.Type: GrantFiled: June 26, 2019Date of Patent: January 5, 2021Assignee: TAE TECHNOLOGIES, INC.Inventors: Yuri I. Belchenko, Alexander V. Burdakov, Vladimir I. Davydenko, Gennady I. Dimov, Alexandr A. Ivanov, Valeery V. Kobets, Artem N. Smirnov, Michl W. Binderbauer, Donald L. Sevier, Terence E. Richardson

Patent number: 10849216Abstract: 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.Type: GrantFiled: June 26, 2019Date of Patent: November 24, 2020Assignee: TAE TECHNOLOGIES, INC.Inventors: Alexander V. Burdakov, Alexandr A. Ivanov, Sergey S. Popov
