摘要: A low voltage (50 kV), energy (3 J) x‐ray preionization source has been developed specifically for avalanche discharge laser preionization. The new device uses a single stage high‐voltage capacitor switched by gradient grid hydrogen thyratron that drives cold‐cathode electron beam. Intense emission is produced allowing the e beam to impact high Z target foil. entire system can operate up 35 Hz repetition rate and produce an density of ∼108 cm−3 in most rare‐gas/halide gas mixtures.
