Paper Abstract

The possibility of creation of capacitive discharge excilamps with short pulse duration was studied. There were three types of pulsed excilamps in experiments: cylindrical glow discharge lamp, capacitive discharge lamp, high pressure volume discharge planar lamp with UV-preionization of discharge gap. In capacitive discharge cylindrical KrCl-excilamp, at (lambda) approximately 222 nm the radiation pulse power through the end face of a lamp up to 2.5 kW has been obtained. Powerful radiation pulses of 50 ns in duration were obtained at pulse repetition rate of 1 kHz. In case of high pressure volume discharge at operating pressure of several atmospheres the radiation peak power density values were as much as 5 kW/cm2 at (lambda) approximately 250 nm, and 3.5 kW/cm2 at (lambda) approximately 222 nm and at (lambda) approximately 308 nm. In cylindrical longitudinal excilamp with inner electrodes with Xe- I2 mixture the total pulse power of 75 kW has been obtained. The first experiments with harnessing of inductive energy stores for excilamp excitation have been carried out.
