Hollow Cathode Discharge Initiation and Fast Starting Cathode
Conditioning of the insert inside a hollow cathode is believed to be important to ensure reliable discharge initiation and subsequent cathode operation. The desorption of contaminates is reported from hollow cathodes as a function of heater power to quantify cathode conditioning characteristics and identify factors that might prevent the fast initiation of a discharge. In addition to conditioni...
متن کاملMeasurement of lithium and sodium metastable quartet atoms in a hollow-cathode discharge.
We report the measurement, in a pulsed hollow-cathode discharge, of metastable quartet atoms of Li and Na. By using a tunable probe laser, population densities of 3x10(10) atoms cm(-3) and 10(11) atoms cm(-3) were measured in the Li(1s2s2p)4P degrees and Na(2p(5)3s3p)(4)D(7/2) levels, respectively. These levels are candidates for energy storage for extreme-ultraviolet lasers.

متن کاملHollow cathode and hybrid atmospheric plasma sources*
Generation and features of the radio frequency (RF) hollow cathode discharge (HCD) are compared for the atmospheric and moderate pressures. The atmospheric-pressure plasma systems, fused hollow cathode (FHC) and hybrid hollow electrode-activated discharge (H-HEAD), are described. Examples of applications where both FHC and H-HEAD have already been employed are given, and potentials for new proc...
متن کاملP1-25: CW Microwave Radiation Source from Micro-Hollow Cathode Plasma Discharge
A continuous-wave microwave radiation source is under investigation using Micro-Hollow Cathode Discharge (MHCD) technology. Arrays of grooves, 50 microns in diameter and ~3 mm long have been fabricated to contain the plasma discharge. Argon discharge in the resonance cavity has been observed at atmospheric pressure. The turn-on voltage was observed to be 400V (383μA). Lowering the voltage to 31...
