ABSTRACT
Abstract. A new high-density gas puff target for experiments on laserdriven x-ray lasers is presented. The target is based on a double-stream gas puff target approach, which makes possible to form elongated gas sheet with steep density gradient and high density of gas in the interaction region. In the paper the valve system to produce the gas puff targets and the results of the target characterization measurements performed using x-ray backlighting technique are presented.
