Generation of stable mixed-compact-toroid rings by inducing plasma currents in strong E rings

In the RECE-Christa device, hybrid-type compact toroid rings are generated by inducing large toroidal plasma currents I/sub p/ in strong electron rings using a thin induction coil positioned along the ring axis. Starting from field-reversal values delta /sub p/=50-120% of the original pure fast-electron ring, the induced plasma current I/sub p/ raises delta to a maximum value of up to 240% with I/sub p/ contributing more than 50% of the total ring current. The generated hybrid compact toroid configurations appear gross-stable during the full I/sub p/ pulse length (half-amplitude width about 100 mu s).<
