The lateral distributions of the laser photoionized neodymium ion at the ion energy between 1400eV and 300eV were measured with a multi-channel Faraday cup. The obtained ions were collimated within these energy regions, and are considered to be useful for the applications of the laser photoionized ions.

The collimation properties of a Neodymium ion beam extracted from a laser photoionized plasma were measured by scanning a multichannel Faraday cup. The ion beam was collimated at the position of the Faraday cup by the electric field produced with a pair of semispherical electrodes set at the extraction electrode. The central ion beam intensity was increased about 36 times. The results were useful for the applications of laser photoionized ion source.

Measurements of collimation property of laser photoionized Neodymium ion beam

For the application of laser photoionized ion beam, intensity distribution of extracted ions was measured with a multi-channel Faraday cup. In order to suppress beam divergence, hemi-cylindrical electrodes for collimation were used, and the lateral divergence of the ion beam was reduced. With hemi-spherical electrodes, lateral and vertical divergence was also reduced, and the central beam intensity was increased.

The intensity distributions of a neodymium ion beam from laser photoionized plasma were measured by scanning a multichannel Faraday cup. The lateral width of ions at the position of the Faraday cup, which was broad without any additional electric field, was reduced by the additional concentric potential with a pair of semicylindrical electrodes set outside of the extraction electrode. The central ion beam intensity increased by about two times with these electrodes. These results were useful for the application of the laser photoionized ion beam.
