A NEW MULTIPOLAR MODE IN BOUNDED GYROTROPIC PLASMA,
Abstract
Multipolar modes in a cylindrical, axially magnetized, cold, collisionless plasma that propagate near the cyclotron frequency are studied quantitatively. Examination of electromagnetic field patterns shows that in addition to the well-known spectrum of cyclotron modes there exists at positive azimuthal eigenvalues (n>0 in exp jn o) a mode that is distinguished by a different type of field pattern. The electric field of this mode is predominantly solenoidal, in contrast to the cyclotron modes where a substantial part of the electric field is laminar. This mode may be of importance in thick-beam parametric amplifiers at microwave frequencies (X-band) and in beam-plasma interaction near cyclotron frequency. (Author)
