Enhanced laser ion acceleration from mass-limited targets

Original language description

Laser interactions with mass-limited targets are studied here via numerical simulations using our relativisti electromagnetic two-dimensional particle-in cell code including all three-velocity components. Analytical estimates are derived to clarify the simulation results. Mass-limited targets preclude the undesirable spread of the absorbed laser energy out of the interaction zone. Mass-limited targets, such as droplets, are shown here to enhance the achievable fast ion energy significantly due to an increase in the hot electron concentration. For given target dimensions, the existence is demonstrated for an optimum laser beam diameter when ion acceleration is efficient and geometrical energy losses are still acceptable. Ion energy also depends on the target geometrical form and rounded targets are found to enhance the energy of accelerated ions.

Zesílené laserové urychlování iontů z terčů s omezenou hmotností

Czech description

Interakce laserového záření s terči s omezenou hmotností je studována pomocí našeho dvojdimenzionálního elektromagnetického PIC kódu (kód částice v síťce) se třemi složkami rychlosti. Jsou odvozeny přibližné analytické vzorce, které objasňují výsledky simulací.
