Observations of hollow cathode light emission from a transient hollow cathode discharge

Applied Physics Letters, 1991
Experimental observations are presented on the light emission from the hollow cathode region of a pulsed hollow cathode discharge. A 2 mJ, 30 ns, 1.06 μm laser pulse incident on the back of the cathode is used to trigger the discharge. The temporal evolution of the light emission from this region is recorded in 50 nm spectral bands.

Hollow cathode chemical modelling [PDF]

, 2008
In this paper the state of hollow cathode life time modelling at the University of Southampton will be reported. Two models have been developed: one for BaO depletion from the hollow cathode insert and another for low work function compounds deposition and desorption.

Physical Processes in Hollow Cathodes

AIAA Journal, 1976
Hollow cathodes with cavity diameters of 1.9 cm have been operated in an MPD arc configuration at discharge currents from 0.25 kA to 30 kA. Current and potential distributions, measured with probes in the cathode cavity, show that a spontaneous mode of hollow cathode operation, wherein the current distribution penetrates upstream into the cavity, has ...

Hollow cathode magnetron

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1999
A new type of plasma sputtering device, named the hollow cathode magnetron (HCM), has been developed by surrounding a planar magnetron cathode with a hollow cathode structure. Operating characteristics of HCMs, current–voltage (I–V) curves for fixed discharge pressure and voltage–pressure (V–p) curves for fixed cathode current, are measured.

Hollow Cathode Discharge with Thermionic Cathodes

Journal of Applied Physics, 1971
The electrical and visual characteristics of a dc hollow cathode discharge with indirectly heated thermionic cathodes were obtained in argon at a few Torr. Two facing planar cathodes of variable separation form the hollow cathode geometry. A hollow cathode effect was observed in the ``ball-of-fire'' mode and in the ``low-voltage arc'' mode. The results

Collisionless instability of the cathode sheath in a hollow-cathode discharge

Physical Review Letters, 1993
High-intensity periodic variations of the potential fall across the cathode sheath are observed in a low-pressure magnetic-field-free hollow-cathode discharge. These potential variations cause modulation of the discharge current, reaching a depth of almost 100%.
