    Abstract

    Plasma expansion into vacuum and resultant ion acceleration is theoretically studied, where the expansion of an initially uniform nanoparticle with radius Rf0 and electron density ne0 is driven by explosion of thermal electrons with initial temperature Te0. Such key outputs as the energy spectrum and maximum ion kinetic energy are explicitly given as a function of Rf0, ne0, and Te0. The simulation results turn out to be well reproduced by a self-similar solution, which describes non-relativistic expansion of a finite plasma mass with a full account of charge separation effects.
