Abstract
The intense voltage spikes of about 10 mus width in high voltage direc t current (dc) axial discharges, particularly, in continuous wave (cw) CO2 laser systems, are analyzed by a bound plasma model subject to ex ternal circuit constraint. The spikes, whose amplitude grows from cath ode to anode, are believed to be a manifestation of the convective spa ce-charge instability of the ion acoustic plasma-circuit mode.
