CAPEX-U - A New Driver for Discharge-Pumped Lasers Working on the Wavelength Below 15 nm

摘要

CAPEX-U device is a pulse-power apparatus capable to deliver a "short-circuit" discharge current -120 kA in a quarter-period ~80 ns. Its characteristic features are direct optical access to both discharge electrodes, and laser triggering of the main spark gap (for exact synchronization of detectors and applications). It is described, how CAPEX-U joint with SHOW device will be used for soft X-ray amplification on nickel-like silver ions (generated by exploding wire in water), and how the pressure at the SHOW axis was measured.
