Plasma-Parameter Measurements in Transverse Hollow-Cathode Discharges.
Abstract
A primarily experimental investigation of transverse hollow-cathode discharges was conducted to obtain detailed knowledge of the microscopic plasma properties of fundamental importance in gaseous laser action. Spherical probes (0.15 to 0.32 mm diam) were used to measure the plasma properties within a slotted hollow cathode for various gases as a function of pressure, current, radial position, and tube diameter. The primary diagnostic tool employed was the Langmuir-probe second-derivative technique. A harmonic second-derivative system was used to obtain probe data.
