Ions can be effectively accelerated during the interaction of an ultra-intense ultra-short laser pulse irradiating a thin solid target via so-called normal sheath acceleration (TNSA) mechanism. One pivotal questions at this stage research is how to predict properties ions, both from fundamental point view and in light foreseen applications. In context, it desirable have simple but reliable description used extrapolate current results future regimes, which will made available near future,...
This study explores the capabilities of Coherent X-ray Imaging Instrument at Linac Light Source to image small biological samples. The weak signal from samples puts a significant demand on experiment. Aerosolized Omono River virus particles ∼40 nm in diameter were injected into submicrometre focus reduced pressure. Diffraction patterns recorded two area detectors. statistical nature measurements many individual provided information about intensity profile beam, phase variations wavefront and...
Diffraction before destruction using X-ray free-electron lasers (XFELs) has the potential to determine radiation-damage-free structures without need for crystallization.

The experimental feasibility of the laser-driven ion acceleration concept with multi-layered, foam-based targets has been investigated. Targets required features have produced and characterized, exploiting potential pulsed laser deposition technique. In intensity range 1016–1017 W cm−2, they allow us to obtain maximum proton energies 2–3 times higher compared bare solid targets, able reach surpass MeV both low ultrahigh contrast pulses. results two-dimensional particle-in-cell simulations,...
