Ion Heating Measurements on the Centerline of a High-Current Hollow Cathode Plume

Journal of Propulsion and Power, 2018
An experimental investigation into the correlation between ion acoustic turbulence (IAT) and anomalous ion heating in the plume of a 100 A-class LaB6 hollow cathode is presented.

Effect of aging the hollow cathode by sputtering on the analytical precision of the hollow cathode discharge emission source

Analytical Chemistry, 1992
Sputtering changes the analytical performance of the hollow cathode as an emission source. Proper conditioning (aging) of the hollow with sputtering greatly improves precision. Conditioning decreases the blank emission signal and changes the shape of the hollow.

A Plasma Stopper in a Hollow Cathode

Instruments and Experimental Techniques, 2002
A cap with a hole was mounted on the top of a cylindrical hollow cathode. The hole diameter ranged from 10 to 90% of the inner diameter of the hollow cathode. As a result, a plasma “stopper” was formed in the cathode cavity near the hole. The stopper hindered the plasma-forming gas flow from the cathode cavity into the vacuum chamber.

Miniature hollow cathode discharges

International Conference on Plasma Sciences (ICOPS), 1993
Summary form only given, as follows. Reducing the cathode hole diameter to about 100 /spl mu/m makes it possible to extend the pressure range for hollow cathode discharge operation to atmospheric pressure. For a submillimeter hollow cathode discharge in neon (at 100 Torr) it was shown that the flow of material in the cathode transforms the originally ...

A Study of Hollow Cathode Discharge Characteristics

AIAA Journal, 1970
The operation and performance of small-orifice hollow cathodes for use in electron bombardment ion thrusters is described. Using mercury propellant, vaporized either in a small boiler or by a heated porous plug, cathodes have been operated in both a simple test facility and in an ion thruster.
