Abstract

A double stream gas puff was proposed as a target for a laser pulse in a soft x-ray source, to overcome a problem of 3D gas flow outside the sonic nozzle. In a case of the sonic nozzle the gas density drops dramatically with a distance from the nozzle outlet. The double stream gas puff target is created by an injection of high Z gas into a hollow stream of low Z gas. Such a solution allows to decrease an x-ray absorption in cold gas and to keep the inner gas at a relatively high density on a distance up to 2mm from the nozzle outlet. Also in this case plasma emitting soft x-rays created by the laser pulse on the distance over 1mm from the nozzle outlet would not destroy it.
