Abstract
In this paper we report the experimental implementation of a theoretically-proposed technique for creating a photoionized plasma in the laboratory using X-ray line radiation. Using a Sn laser-plasma to irradiate an Ar gas target, the photoionization parameter , ξ = 4πF/Ne, reached values of order 50 erg cm s-1 , where F is the radiation flux in erg cm-2s-1. The significance of this is that this technique allows us to mimic effective spectral radiation temperatures in excess of 1keV. We show that our plasma starts to be collisionally dominated before the peak of the X-ray drive, However, the technique is extendable to higher energy laser systems to create plasmas with parameters relevant to benchmarking codes used to model astrophysical objects.
