| 内容記述 | Ion acceleration using a laser pulse irradiating a thin disk target is examined using three-dimensional and two-dimensional particle-in-cell simulations. A laser pulse of $620$ TW, with an intensity of $5\times 10^{21}$ W/cm$^{2}$ and a duration of $27$ fs is irradiated on to a double-layer target. Simulations are performed by varying the ion density, i.e., electron density, of the first layer with a fixed areal mass density. It is shown that the obtained proton energy increases dramatically for a certain density of the first layer, which is made of a material having a small mass over charge ratio, ``light'' material, such as carbon; that is, the Coulomb explosion of the target and radiation pressure acceleration act effectively above a certain density. Moreover, even for the same electron density, the reflection of the laser pulse from the first layer is small for a ``light'' material. |
