Název v původním jazyce

Plasma shutter for laser-driven ion acceleration

Popis výsledku v původním jazyce

A plasma shutter is usually a thin solid foil or membrane which is placed in front of the main target in the laser-matter interaction. The laser pulse then needs to burn through the shutter, shaping its intensity profile. It can be used for mitigation of the prepulse (as was already demonstrated in the experiments and also for the shaping of the main pulse itself, resulting in the generation of a steep-rising front and local intensity increase of the transmitted laser pulse. In this work we study the use of a commercial silicon nitride membrane as the plasma shutter in the interaction with a PW-class laser (corresponding to systems like ELI Beamlines) and subsequent interaction of the transmitted laser pulse with a silver foil Several 2D and 3D particle-in-cell simulations using the code EPOCH and 2D hydrodynamic simulations done by the code PALE were employed. The plasma shutter in our 3D PIC simulations resulted in a generation of a steep-rising front and local intensity increase of the transmitted laser pulse by a factor of 7. Subsequently, the maximal energy of silver ions accelerated from the target located behind the shutter increases by 35%. The divergence of the generated ion beam is significantly reduced. A scheme employing a double plasma shutter was proposed and a prototype was prepared, resulting in significant increase of maximal ion energy compared to the case without any plasma shutter.
