Improvement of energy conversion efficiency from laser to proton beam in a laser foil interaction
Result description
A multihole thin-foil target is proposed in order to increase the energy-conversion efficiency from laser to protons. The multiholes transpiercing the foil target help to enhance the laser-proton energy-conversion efficiency significantly. Particle-in-cell 2.5-dimensional simulations present that the total laser-proton energy conversion efficiency becomes 9.3% for the multihole target, though the energy-conversion efficiency is 1.5% for a plain thin-foil target.

Zlepšení konverze energie laseru do protonového svazku při interakci laseru s fólií
Czech description
Je navrženo užití fólie s mnoha děrami pro zvýšení účinnosti transformace energie laseru do urychlených protonů. 2,5-dimensionální simulace metodou "Částice v buňce" (Particle-In-Cell) ukazují, že pro terč s mnoha děrami účinnost je 9,3%, zatímco pro rovinnou fólii je ve stejných podmínkách jen 1,5%.
