Abstract
This paper presents a method for enhancing the ablation plasma production and the flyer velocity for flyer acceleration. A significant approach introduced is to optimize the interaction field of the ablation plasma and the Al target. To do so, it is acceptable to adjust the distance of ion beam irradiation. A onedimensionalhydrodynamic model is used in the calculations.The cubeinterpolated propagation (CIP) method is used to describe the ablation plasma production and the acceleration mechanism. In the calculations, a singlepulsedion beam with a total energy density of 120 J/cm 2 is used. The interaction field (ion beam irradiation distance) that varies from 50 to 1000 m is fixed for the calculations. At the interaction field of 50 μm, the flyer velocity of 2 km/s is calculated, while the value of 1.3 km/s is obtained at the distance of 400 μm. The results show that the closer the interaction field (distance of ion beam irradiation), the higher the flyer velocity obtained. In addition, the results reveal that the interaction field directly affects the amount of the ablation plasma produced and the flyer momentum.
