Paper Abstract

We have tested a high-repetition-rate X-ray diode working in reflection geometry, which uses commercial spark-plugs as plasma cathode. The results show that the spark-plug plasma cathode is a reliable, high-current and long-lifetime electron gun. After more than 106 shots, the dose, uniformity and ionization rate of the emitted X-ray guarantee an effective preionization of XeCl excimer laser discharges. Due to the low cost, the long lifetime and the substantial absence of maintenance, this X-ray diode seems suitable to preionize commercial gas lasers, such as excimer and TEA CO2 lasers.
