Description
| - V tomto článku je prezentován analytický model urychlování kvazimonoenergetických iontů v terčích sestávajících se z více druhů iontů a ozařovaných intenzivním laserovým zářením. Analytický model je doplněn počítačovými simulacemi založenými na metodě particle-in-cell a porovnán s experimentálními výsledky. Z teorie vyplývá, že interakce mezi težkými a lehkými ionty hraje významnou roli ve formování a udržení kvazimonoenergetického spektra lehkých iontů. (cs)
- The paper presents an analytical model and particle-in-cell simulations of the quasi-mono-energetic ion acceleration by an intense laser pulse in a multispecies target and the corresponding experimental observations. Homogeneous and heterogeneous targets are considered, and it is shown that the formation of the energy spectrum proceeds in three stages: 1) the initial light ion acceleration in the sheath electric field, 2) the ion species separation followed by the electrostatic shock formation, and 3) the interaction of spatially separated ion bunches accompanied by electron cooling. The field ionization of heavy ions and interaction between the heavy and light species play an important role in the formation and preservation of the energy spectrum of light ions. The simulation results are compared with the theoretical predictions and the experiments.
