X-ray laser experiments by using a gas puff target with the ASTERIX IV facility
- Institute of Optoelectronics, Military University of Technology, Warsaw (Poland)
We report the first X-ray laser experiments with the use of laser-irradiated gas puff targets. The targets, produced by pulsed injection of a small amount of gas from a high-pressure solenoid valve through a nozzle in a form of a slit, has been characterized by optical interferometry and X-ray backlighting. The formation of elongated hot plasma columns up to 30-mm long is demonstrated. The spatial uniformity of the column was monitored by means of an X-ray pinhole camera. XUV spectra measurements for SF{sub 6} gas puff targets show predominant 3{endash}2 line of hydrogenic fluorine ({lambda}=8.1 nm), however, only linear increasing of its intensity with the target length was observed. An inversion on the lithium-like 4{ital d}-3{ital p} line can be inferred from the relative intensities of the Li-like resonance lines. Results for Kr target indicate that the plasma temperature was too low to create Ne-like ions. {copyright} {ital 1996 American Institute of Physics.}
