Highly ionized hollow cathode discharge

Webradiation source based on using a Micro-Hollow Cathode Discharge (MHCD) as the plasma generator. MHCD plasma sources produce discharges between a cathode, which has a hollow structure, and an arbitrarily shaped anode [5]. The structure of the cathode can be of any size, but in order to operate the device at atmospheric WebHollow anode discharge represents a new type of discharge which is realized in a diode consisting of a concave cathode and a special type of hollow anode whose inner surface only is conductive.
