Abstract
We present experimental observations of ionization waves in pulsed
hollow cathode capillary discharges. When the capillary shield is at the
anode potential, an anode directed ionization wave, with characteristic
speed ∼107 m/s, is observed. When the capillary shield is
at the cathode potential, a cathode directed slower ionization wave,
with characteristic speed ∼104 m/s, is observed. The
several orders of magnitude difference in the ionization wave speed can
be attributed to the different initial electric field configuration in
both polarities.
