46th International Workshop on High Energy Density Physics with Intense Ion and Laser Beams

Magnetic lens-based proton radiography is a unique and powerful diagnostics technique capable of resolving ultra-fast processes on the ns-scale in dense matter with unprecedented micrometer spatial resolution. Recently, the PRIOR-II proton radiography facility has been designed, constructed and commissioned at the GSI Helmholtz Centre for Heavy Ion Research, pushing the technical boundaries of...

The HHT experiment area at GSI offers the unique capability to heat matter by intense bunches of high-energy heavy-ions from the SIS-18 heavy-ion synchrotron and to probe the generated short-lived states with X-rays created by the PHELIX laser facility. Focusing ~300-ns-long bunches of up to $4\times 10^9$ $\text{U}^{73+}$ ions down to sub-millimeter spot-sizes, aluminum samples were heated to...

The graphitization-threshold of diamond is of significant interest for nanodiamond synthesis from laser-shocked plastics, for particle detectors, and for the application in diamond anvil cells.
We report on experiments conducted at the HHT facility (GSI), in which a monocrystalline diamond target was volumetrically heated using a uranium ion beam. The PHELIX laser enabled measurements of...

Accurately determining the ionization state of warm dense carbon is critical
for predictive modeling in high-energy-density physics, particularly for inertial
confinement fusion experiments and for advancing the understanding of astro-
physical systems such as white dwarf envelopes [1,2]. However, obtaining direct
measurements under the relevant extreme conditions remains challenging....
