Comparison of graphite materials for targets of laser ion source

Abstract

To investigate efficient graphite material for carbon ion production in laser ion source, the plasma properties produced from these materials are measured. Comparing acquired current profile and charge state distribution, the distributions of ions in laser induced plasma from isotropic graphite and single crystal of graphite are different. The produced quantity of C6+ from isotropic materials is larger than that from single crystal. © 2014 AIP Publishing LLC.
