Microwave gas exciter for gas discharge path - uses microwave resonator including discharge path and connected to microwave supply line

摘要

The microwave resonator (10) is provided with a local inhomogeneous field strength distribution having at least one region of max. field strength and at least one region with a field strength lying under a threshold value for the ignition of the gas discharge. The gas discharge path (14), excitable by the microwave energy supply in pulses, is arranged exclusively within a region provided for the ignition of the gas discharge, between the field strength max. region and a threshold value border. The gas discharge path is arranged nearer a threshold value border determined by the resonator mode than to the field strength max. region. USE/ADVANTAGE - Known type improved so that determined gas discharge stretch with higher power density is available with unaltered transmitter power. Esp. applicable where the housing of the resonator has a microwave-sealed light emergence window for lamp or flash light, gas laser.
