Abstract
We report measurements of electrical properties and spatial emission profiles of hollow cathode discharge, both for steady state and transient phases during formation of the discharge. A commercial hollow cathode tube filled with neon at 3.5 Torr has been studied. Our aim was to relate discharge anatomy to the voltage-current characteristics in a wide range of the operating conditions. It was particularly interesting to track down in time formation of the discharge structure, which is typical for "hollow cathode effect".
