要約
The results of experimental investigations of influence of external magnetic field on characteristics of ion stream emitted from tungsten plasma produced by the Nd:glass laser (1 J, 1 ns) (performed at IPPLM, Warsaw) are presented. The magnetic field induction of 0.45 T was used in mis experiment. A set of ion collectors and an electrostatic cylindrical ion-energy analyser located at small angles with respect to the laser beam axis and at large distances from the target were applied for ion diagnostics. It was found that the effect of an axial magnetic field causes an effective ion beam compression (focusing) as well as increase of the ion current and decrease of ion velocity (energy) of the ions expanding along the magnetic field. This result is important for optimisation of parameters of ion stream emitted from the laser-produced plasma for particular application as a Laser Ion Source (LIS) coupled with the Electron Cyclotron Resonance (ECR) ion source for particle accelerators (ECLISSE program initiated at INTN-LNS in Italy).
