Source Properties of a Hollow Cathode Arc Plasma

Experiments have been carried out on the properties of a hollow cathode as an ion-source. The measured electron density, ion and neutral temperatures and drift velocities have been compared with predictions from the conservation laws for matter, momentum and energy. Very large exit drift velocities of ions and neutrals are observed. The magnitude and direction, against the electric field, can b...

An interchangeable-cathode vacuum arc plasma source.

A simplified vacuum arc design [based on metal vapor vacuum arc (MeVVA) concepts] is employed as a plasma source for a study of a (7)Be non-neutral plasma. The design includes a mechanism for interchanging the cathode source. Testing of the plasma source showed that it is capable of producing on the order of 10(12) charges at confinable energies using a boron-carbide disk as the cathode target....

Hollow 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...

Direct Measurements of Plasma Properties nearby a Hollow Cathode Using a High Speed Electrostatic Probe

A method is described for mapping the plasma parameters nearby a hollow cathode using a high speed positioning system and a segment-shielded electrostatic probe. Contour maps of plasma density, plasma potential, and electron temperature are presented for wide ranges of discharge current (2 20 A) and xenon flow rate (1.5 – 4.5 sccm). The contour maps are constructed from the analysis of 320 I-V ...

P1-25: 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...
