Publication number: 20240203628Abstract: Described herein are concepts, system and techniques which provide a means to construct robust high-field superconducting magnets using simple fabrication techniques and modular components that scale well toward commercialization. The resulting magnet assembly—which utilizes non-insulated, high temperature superconducting tapes (HTS) and provides for optimized coolant pathways—is inherently strong structurally, which enables maximum utilization of the high magnetic fields available with HTS technology. In addition, the concepts described herein provide for control of quench-induced current distributions within the tape stack and surrounding superstructure to safely dissipate quench energy, while at the same time obtaining acceptable magnet charge time. The net result is a structurally and thermally robust, high-field magnet assembly that is passively protected against quench fault conditions.Type: ApplicationFiled: September 28, 2023Publication date: June 20, 2024Applicants: Massachusetts Institute of Technology, Commonwealth Fusion System LLCInventors: Brian LABOMBARD, Robert S.

Publication number: 20240088773Abstract: A wind turbine generator includes a stator having a plurality of high-temperature superconducting coils. A current is driven through the high-temperature superconducting coils to produce a magnetic field. A rotor comprising one or more phase coils is physically coupled to a wind turbine. As the wind turbine turns the rotor, current is induced in the one or more phase coils to produce electrical power. The phase coils may include conductive material, superconducting material, and/or high-temperature superconducting material.Type: ApplicationFiled: February 8, 2022Publication date: March 14, 2024Applicants: Massachusetts Institute of Technology, Commonwealth Fusion Systems LLCInventors: Alexey RADOVINSKY, Michael SEGAL

Publication number: 20240013960Abstract: A magnet system and method of operating may be used in connection with operating a superconducting electromagnet, for example in a tokamak. The magnet system includes a coil having windings retained within a non-insulated structure, so that current can pass both along the windings to generate a magnetic field, and between the windings. The amount of current passing through the coil is trimmed using a bypass circuit, coupled in parallel to the coil terminals. The bypass circuit is controlled on the basis of measurements of the field components to divert current from passing through the field coil. In this way, the magnetic fields of each of multiple field coils can be brought into mutual uniformity.Type: ApplicationFiled: March 1, 2021Publication date: January 11, 2024Applicants: Massachusetts Institute of Technology, Commonwealth Fusion Systems LLCInventors: Alexey RADOVINSKY, Robert MUMGAARD, Theodore GOLFINOPOULOS

Publication number: 20230097465Abstract: Structures and methods enable emergency or rapid shutdown of an energized no-insulation (NI) superconducting magnet, without damage due to thermal effects of a quench. A resistive bypass wire is coupled between electrical terminals of the magnet coil, and does not pass significant current during normal magnet operation. When rapid shutdown is required, the bypass wire is cooled below its critical temperature, adding a superconducting current path in parallel with the magnet coil. A portion of the coil is then heated above its critical temperature, interrupting current flow through the coil. Hot spots near the coil leads are mitigated through the use of a conductive structure, such as copper cladding, that carries away excess heat due to the quench. This heat may be deposited in a resistive matrix, such as a steel plate, over a duration of seconds and without compromising other magnet design parameters.Type: ApplicationFiled: March 25, 2021Publication date: March 30, 2023Applicants: Massachusetts Institute of Technology, Commonwealth Fusion Systems LLCInventors: Alexey RADOVINSKY, Krishna Kiran Kumar UPPALAPATI

Patent number: 10028369Abstract: Ions are released over time from an ion source into a beam area proximate a central axis. A radiofrequency (RF) system with a variable frequency and variable voltage accelerates the ions in orbiting trajectories expanding outward from the central axis. The ions are accelerated to different extraction energy levels within a given design range at a shared extraction radius from the central axis. An RF-frequency versus ion-time-of-flight scenario is set such that the frequency versus time scenario is the same for any ion extraction energy from the given design range, and a constant-or-variable-RF-voltage versus ion-time-of-flight scenario is adjusted to provide ion acceleration from injection to extraction for ions with different respective extraction energy levels within the given design range; and the ions are extracted at the different energy levels at the shared extraction radius.Type: GrantFiled: March 13, 2017Date of Patent: July 17, 2018Assignee: Massachusetts Institute of TechnologyInventor: Alexey Radovinsky
