Introduction
In recent investigations of wave interaction with intense plasmas sustained
in magnetic multicusps (MCs) [1–4], it was observed that electromagnetic
standing waves (SW) are realized along the axis of the minimally magne-
tized (|B
o
| < 1 gauss) plasma column [2]. The origin of the SW was attributed
to the penetration and inadequate screening of the wave elds reected from
the conducting radial boundary [3,4] and from the axial plasma–vacuum
interface at the ends [2,3]. During the investigation of the SW phenomenon,
measurement of the axial plasma oating potential was perfor ...
