Equilibrium of a Pinch Discharge with a Transverse Rotating Magnetic Field

Abstract

SummaryThe electron density distribution in a linear pinch discharge with a transverse rotating magnetic field is calculated for partially ionized plasmas. Numerical examples are given for distributions in the plasma with and without externally applied axial magnetic fields, and with different degrees of ionization.

Higher Harmonics and Transport Coefficients of Plasmas in Circulary Polarized Magnetic Fields and Additional Electromagnetic Fields

“…In a following paper [4] it hau been shown that overtone oscillations of the rotation frequency o (up to the third) must be taken into account. Other important papers dealing with the problem considered have been given by Kondo and Toshioka [5] (unfortunately, only an abstract was accesible to the authors), by Soldatenkov [6] and, on a more special problem, by Blevin and Miller [7].…”

Field reversal by rotating waves

“…The idea of producing electric current by rotating waves originated with Blevin and Thonemann [3] and has been expanded upon in several other papers [4][5][6][7]. The fundamental principle guiding all relevant theoretical and experimental work is that, in the presence of a rotating field, electrons may be tied to the magnetic field lines when ions are not, so that the field causes a synchronous rotation of electrons rather than ions.…”

Power and Momentum Relations in Rotating Magnetic Field Current Drive

“…The travelling wave field in this experiment was generated by a helical slow wave structure wound around the torus. Rotating magnetic fields were utilized later to drive steady azimuthal currents in cylindrical plasmas (Blevin and Thonemann 1962;Davenport et al 1966;Blevin and Miller 1965;Hugrass et al 1981). The RMF technique is also used to drive the steady current in the Rotamak configuration which is a compact toroidal equilibrium (Jones 1979;Hugrass et al 1980;Durance et al 1982).…”
