Abstract

The experimental results of investigations on influence of external magnetic and electric fields on characteristics of ion stream emitted from a plasma produced by the Nd:glass performed at IPPLM, Warsaw are presented. A negatively biased target up to -15 kV and a magnetic field up to 0.45 T were used in the experiment. A set of ion collectors and an electrostatic cylindrical ion energy analyzer located at small angles with respect to the laser beam axis and at large distances from the target were applied for ion measurements. The effect of an external magnetic field is essential to plasma expansion but the effect of the retarding potential of the target is very weak in our experimental conditions. The presented results relate only to tungsten plasma. The aim of the studies was to prove a possibility of optimization of ion beam parameters from laser-produced plasma for particular application as a Laser Ion Source coupled with the Electron Cyclotron Resonance ion source for particle accelerators.
