Design of an optimized Cluster-Jet Target for CryoFlash — •L. Leßmann, D. Bonaventura, S. Grieser, and A. Khoukaz — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, 48149 Münster, Germany

The CryoFlash experiment investigates the interaction of the high intensity, short-pulse Ti:Sa laser of the Arcturus Facility Düsseldorf with a cryogenic cluster-jet target constructed at the University of Münster. The main fields of research are the generation of femtosecond X-ray pulses for pump-probe experiments and furthermore the acceleration of electrons and ions up to the MeV scale within a tabletop setup. The cluster-jet target provides a continuous flow of micro- to nanometer sized particles which are of approximately solid density by pressing pre-cooled gas through a Laval nozzle. This combines the advantages of gas-jet targets (continuous flow) and solid targets (high density).

A first cluster-jet target, constructed at the University of Münster, has already been installed at the Arcturus Facility Düsseldorf. First measurements of the interaction of the high intensity, short-pulse laser with the cluster-jet have been taken. The results and experience of the first measurements have been used to design a new and optimized cluster-jet target. The concept and design of this new target will be presented and discussed.
