| contents | Generation of quasi-monoenergetic ion pulse by laser-driven acceleration is one of the hot topics in laser plasma physics. In this study, we present a new method for the \textit{In-situ} deposition of an ultra-thin D$_2$O layer on the surface of an aluminum foil target utilizing a spherical D$_2$O capsule. Employing a 10$^{19}$ W/cm$^2$ laser, we achieve the acceleration of 10.8 MeV deuterons with an energy spread of $Δ$E/E = 4.6% in the most favorable shot. The energy spread depends on the exposure time of the D$_2$O capsule in the vacuum chamber. This method has the potential to extend its applicability to other ion species. |
