A Dual-driven Hard X-ray Source as Benchmark for High Brilliance Lab-based X-ray Generation — •Lion Günster, Luka Petersen, Jose Mapa, Greta Paruschke, Philip Mosel, Sven Fröhlich, Andrea Trabattoni, Uwe Morgner, and Milutin Kovacev — Leibniz Universität Hannover - Institut für Quantenoptik, Hannover, Deutschland

Conventional X-ray sources have been stagnating in terms of brightness. Melting of target or anode material caused by the electron beam limits conventional sources to a brilliance of <10¹⁰ Photon/s mrad² mm². However, it has been proposed that secondary sources could be the key to advance lab based hard x-ray sources and with the rapid improvements of high energy short pulsed lasers promising results have been achieved.

In my poster I will demonstrate the construction of an apparatus that employs a Galinstan liquid metal jet as target material and allows the switching between an electron beam and a laser produced plasma (LPP) to drive the generation of x-rays without modifying any other experimental parameters. In that way, the apparatus allows a direct comparison between conventional and secondary x-ray sources, which has not been conducted yet.

Keywords: x-ray; laser produced plasma; plasma; secondary sources; high brilliance
