 note = {In the recent experiment concerning high power laser-cluster interaction, composed of CO2 clusters and background hydrogen gas, conducted at JAEA-KPSI, high energy background hydrogen ions, accelerated up to 1.6 MeV, have been observed. In order to examine the acceleration mechanism of the background gas ions, we have performed 2D and 3D PIC simulations in the parameter regime relevant to the experiment. The simulation results shows that at the contact surface area, the asymmetric electric field of Coulomb explosion from cluster and the additional electric field from background gas are generated and these electric fields contribute to the acceleration of background gas ions. From energy spectra of ions, the simulation results well support experimental ones., High Energy Density Sciences 2016},
