Resumen

The ECLISSE project (ECR ion source Coupled to a Laser Ion Source for charge State Enhancement) started in 1999 with the aim to obtain intense beam of highly charged ions (pulsed mode) by means of the coupling between a Laser Ion Source (LIS) and an electron cyclotron resonance (ECR) ion source. The major points to be investigated appeared to be the coupling efficiency of the ion beam produced by the LIS to the ECR plasma, as well as the possibility to enhance the available charge state by an ECRIS with respect to the standard methods used now to produce ion beams from solid samples (i. e. evaporation and sputtering). The theory suggests that this concept may be effective, provided that the ion energy from the LIS is of the order of a few hundreds of eV. The main features of the theory will be shown in the following, along with the results obtained in the off-line test at LNS facility (Nd: YAG laser 0. 9 J / 9 ns, laser power densities < 10¹1 W/cm²) and at IPPLM facility (Nd: glass laser 10 J / 1 ns, limited to 1. 5 J).
