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 WebJan 9, 2008 · Hollow cathode arc discharge as an effective energy source for welding processes in vacuum - IOPscience This site uses cookies.

WebNov 1, 1997 · In the same pD range, but at higher currents of up to approximately 4 mA, the discharges are of the hollow cathode discharge type. At pD values exceeding 5 Torr cm … WebJun 11, 2004 · A hollow cathode discharge (HCD) is described that produces a highly ionized steady‐state plasma (n e ≈10 13 −10 14 /cm 3) at a temperature 1–10 eV, in a …
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. WebThe low pressure glow discharges considered in this paper are the hollow cathode (Paschen), and the flat cathode (Grimm). Both discharges have similar voltage-current characteristics which are responsible for their radiation stability. The analytical sample is supplied to the discharge through a sputtering mechanism which provides a stable and ...
