Abstract : The research covers hollow cathode discharge (HCD) mechanisms and instabilities. Positive column theories of steady state magnetized discharges are extended to finite cylinder geometries by separation of variables. Low frequency instabilities in HCD's are identified as centrifugal flute modes driven by non-uniform E/Br rotation and stabilized by infinite Larmor radius effects. (Author)
