Experimental studies of the rotational stability of a tandem mirror with quadrupole end cells

Description
It is demonstrated that the radial electric field in the Phaedrus Tandem Mirror [Plasma Physics and Controlled Nuclear Fusion Research 1984 (IAEA, Vienna, 1985), Vol. 2, p. 265] can be altered using plasma potential control rings (PPC rings) situated at each end of the device, and the azimuthal plasma rotational velocity may thus be varied. Low-frequency (ω much-lt ωci), low azimuthal mode number (m=-1 and m=-2) instabilities driven by ExB rotation are observed and shown to be in qualitative agreement with the theory of Freidberg and D'Ippolito [Phys. Fluids 26, 2657 (1983)], and Phillips [Phys. Fluids 27, 1783 (1984)] for the case when Phaedrus is operated as a conventional tandem mirror with minimum-|B| end cells
