Abstract
For ion-mode plasma containment, a toroidal vacuum vessel (322) has a major radius (208) and a minor radius (212). The toroidal vacuum vessel (322) is filled with a gas (391) having an initial particle density. An ionizing device (341) ionizes the gas (391) into a plasma (400). A transformer inductively (326) drives a toroidal particle current (332) comprising an ion current and an electron current about a toroidal axis. The toroidal particle current (322) heats the plasma (400) and generates a poloidal magnetic field (373). Field coils (414) wound poloidally about the toroidal vacuum vessel (322) generate a toroidal magnetic field (371). The toroidal magnetic field (371) at a wall of the toroidal vacuum vessel (322) is adjusted to satisfy a boundary condition for a minimum-energy. The plasma (400) is contained by the radial electric field, the poloidal magnetic field (373), and the toroidal magnetic field (371) within the toroidal vacuum vessel (322) in the minimum-energy state.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
