Abstract

High-pressure gas discharge experiments are carried out in a novel three-electrode prepulse-mainpulse configuration with two discharge volumes. The design is capable to break down both x-ray preionized volumes at the same time. First experiments in Xe/HCl/Ne mixtures reveal spatially very homogeneous discharges for up to 350 ns with a power deposition of 260 kW/cm³. For discharges in Kr/HCl/Ne mixtures we observe also very homogeneous discharges for a similar long pulse duration when a low krypton concentration of 10 mbar is used. For discharges in mixtures with a higher krypton concentration of 100 mbar we still observe very homogeneous discharges for 200 ns. Furthermore the total discharge current is established 8-10 times faster than in other systems.
