High-intensity lasers can accelerate protons through mechanisms such as target normal sheath acceleration, producing beams with picosecond pulse durations, high charge and low emittance. These beams are desirable for applications such as radiobiology, warm dense matter and radioisotope generation; however, for these applications to become viable, challenges that need to be addressed include...
Over the last few years, research at the laser-driven ion acceleration (LION) beamline at the Centre for Advanced Laser Applications (CALA) in Garching near Munich has been established. The setup is powered by the Petawatt-class ATLAS-3000 Ti:Sa laser operating at 1 Hz. Currently, up to 13 J in 28 fs are focused to a 5 $\mu$m FWHM focal spot, reaching peak intensities $>10^{20}$ W/cm$^2$. To...
Improved control of high intensity laser beam parameters on target recently enabled proton energies beyond 100 MeV, dose-controlled sample irradiation experiments, and the demonstration of seeded FEL light.
This presentation focuses on the chain of developments at the Petawatt laser DRACO that enabled systematic studies in the regime of relativistic target transparency for thin foil as well...
Nanostructured solid targets have gained significant attention in high-intensity laser-plasma interaction due to their potential to improve laser absorption, enhance particle acceleration, and enable access to extreme-energy-density states [1].
However, experimentally probing the interaction dynamics and critical plasma properties remains challenging, as their evolution occurs on nanometer...
When a high-intensity laser interacts with matter, many processes lead to the generation of intense electromagnetic fields, in a spectrum ranging from MHz to THz, known as electromagnetic pulses(EMPs). The effects of the EMPs on the instrumentation are long-time studied topic, especially in laser-driven ion acceleration or nuclear-fusion experiments.
We studied the evidence of such fields on...
In recent years, sources of polarized beams from laser-plasma interaction have gained significant interest in the accelerator community [1]. Possible applications of such beams range from basic research, e.g. deep-inelastic scattering, to enhanced energy production in fusion reactors. It was shown by Kulsrud et al. that in the case of the reaction $d + t\to \alpha + n$, the cross-section is...
