  • System and method for controlling plasma magnetic field
    Patent number: 9967963
    Abstract: Examples of a system for generating and confining a compact toroid are disclosed. The system comprises a plasma generator for generating magnetized plasma, a flux conserver for receiving the compact toroid, a power source for providing current pulse and a controller for actively controlling a current profile of the pulse to keep plasma's q-profile within pre-determined range. Examples of methods of controlling a magnetic lifetime of a magnetized plasma by controlling a current profile of the current pulse are disclosed.
    Type: Grant
