| 英文摘要 | We propose a focusing mechanism of high-energy ions by in electron cloud produced by a laser interaction with slab plasma. In our 2.5-dimensional (2.5D) particle-in-cell simulations. the laser intensity is 2 X 10(20) W/cm(2), the laser wavelength lambda is 1.053 mu m, and the laser spot size is 2.5 lambda. When the high intensity laser irradiates slab plasma. electrons are accelerated, oscillate around the plasma and produce the electron cloud locally at the sides of the plasma. Because the electrons are localized transversely, a static electric potential is formed to focus ions and at the same time the ions are accelerated longitudinally. Though the longitudinal ion acceleration has been studied well, the ion focusing effect is reported for the first time in this paper. In our calculations, the maximum energy and intensity of the protons are 8.61 MeV and 1.89 x 10(17) W/cm(2), and the diameter of the proton bunch accelerated are focused to 71.2% of its initial size. |
