In order to increase the beam intensity of a laser ion source extracted from laser photoiomzed plasma, a pair of semispherical electrodes was set outside the conventional parallel plate electrodes, and the obtained intensity distributions were measured by scanning a multichannel Faraday cup. The vertical and horizontal widths of the ion beam at the position of the detector were reduced by the concentric electric field formed with these electrodes. The central ion beam intensity increased about 36 times compared with that in the case without the additional electric field. The ion trajectories as a function of the potential applied to the electrodes and the initial emergent position on the electrode were studied by simulations using SIMION 3D 7.0 software package.
