Abstract
A compound plasma configuration can be formed from a device having pins, and an annular electrode surrounding the pins. A cylindrical conductor is electrically connected to, and coaxial with, the annular electrode, and a helical conductor coaxial with the cylindrical conductor. The helical conductor is composed of wires, each wire electrically connected to each pin. The annular electrode and the pins are disposed in the same direction away from the interior of the conducting cylinder.
Claims9
A method for forming a compound plasma configuration, comprising:
- driving an impulse current through a helical conductor, a gas, and an annular electrode thereby forming an annular plasma between an end of said helical conductor and said annular electrode;
- generating an axial magnetic field threading through said annular plasma while increasing said impulse current driven through said helical conductor and said annular electrode;
- and
- generating an azimuthal magnetic field around said axial magnetic field while further increasing said impulse current driven through said helical conductor and said annular electrode, said azimuthal magnetic field differentiating said annular plasma into a plasma sheath and a central plasma channel.
