Abstract

In this work a double stream ga puff target was applied in experiments connected with a laser plasma soft x-ray source. The results of the gas puff target density measurements was presented. The experimental results of x-ray measurements concern two experiments. The first one was performed in the Institute of Optoelectronics using 1 ns Nd:glass laser. In this experiment soft x-ray radiation around 1 keV and 3 keV was investigated. The measurements were performed using an x-ray pinhole camera, a flat crystal spectrograph and a soft x-ray photodiode. The second experiment was performed in the Institute for Plasma Physics using a 27 ns KrF laser. In this experiment EUV radiation of the wavelength around 13 nm from the gas puff plasma was measured using a multilayer mirror combined with an x-ray detector. In both experiments it was shown that the emission from the plasma created in the double stream gas puff target was even an order of magnitude higher than in a case of using the ordinary gas puff target.
