State-of-the-art laser-driven plasma accelerators are entering the Hz repetition-rate regime, delivering ion beams with cut-off energies of multiple tens of MeV. For many applications, this creates an urgent need for a precise online dose monitor that can cope with the challenges of these sources and is capable of reconstructing the full dynamic range of the exponential dose...

Efficient DLA electron and proton acceleration from near-critical density is studied experimentally and in 3D PIC simulations. The 3D PIC simulations have shown that a smoothed density increase is favourable for DLA and leads to a higher effective temperature of accelerated electrons than in the case of a constant density plasma slab

Magnetic lens-based charged particle microscopy 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 microscope facility has been designed, constructed and commissioned at the GSI Helmholtz Centre for Heavy Ion Research, pushing the technical...

We present experimental results from the HHT experimental area at GSI, demonstrating a robust method for single-shot focal spot characterization of the SIS18 heavy ion beam (238 U73+, 300 MeV/u).
The diagnostic setup utilized a Si (444) spherically bent crystal spectrometer coupled with a CCD camera to record the Cu K-alpha emission (8.048 keV) induced by the ion interaction with a thick...
