Abstract

Intensity distributions of a neodymium ion beam, which was extracted from a laser photoionized plasma were measured by scanning a multichannel Faraday cup. The lateral width of ions at the position of the Faraday cup was broad without any concentric electric field, and it was reduced by an application of a concentric potential produced using a pair of semicylindrical electrodes set outside the extraction electrode. The ion beam was further collimated by the electric field produced using a pair of semispherical electrodes. The central ion beam intensity with these electrodes was increased about 36 times compared without additional electric field. The results were useful for applications of laser photoionized ion beams.
