Abstract
A high performance field reversed configuration (FRC) system includes a central confinement chamber, two divertor chambers coupled to the chamber, and two diametrically opposed spheromak injectors coupled to the divertor chambers. A magnetic system includes quasi-dc coils axially positioned along the FRC system components.
Claims17
A method for generating and maintaining a magnetic field with a field reversed configuration (FRC) comprising the steps of:
- injecting first and second spheromak plasmas from opposing first and second spheromak injectors axially towards the mid-plane of the chamber, merging the first and second spheromak plasmas and forming an FRC about the merged plasma in a confinement chamber, and maintaining the FRC at or about a constant value without decay by injecting beams of fast neutral atoms from neutral beam injectors into the FRC plasma at an angle towards the mid-plane of the confinement chamber;
- Wherein one of injecting spheromak plasmas from the first and second spheromak injectors having magnetic flux greater than 20 mWb or injecting spheromak plasmas from the first and second spheromak injectors having magnetic flux greater than about 25-30 mWb.
