Abstract

The ECLISSE experiment performed at INFN-LNS in 2002 with the superconducting ECR ion source SERSE proved the possibility to couple a laser ion source (LIS) with an electron cyclotron resonance ion source (ECRIS) in order to obtain cw ion beams from refractory metals with characteristics that are not achievable with standard LIS. The oven that is used for the production of vapors inside the ECRIS fails with refractory elements and the sputtering method is not adequate for the production of beams with intensity above a few tens of micro ampere. So the use of a LIS inside the ECRIS plasma chamber may permit to obtain the advantage of a LIS in terms of beam current with the typical features of an ECRIS (high charge states, cw mode operation, relatively low emittance). One of the limiting factors of the previous experiment was the relatively low plasma density of the previous generation ECRIS, working at a frequency between 14 and 18GHz. Nowadays the availability of third generation ECRIS (operating at 28GHz or higher, i.e. with a plasma density four times larger) may extend the capabilities of this method, as the denser plasma may catch ions from LIS with energies up to about 1keV per charge state, much higher than it is possible for sources operating at lower frequency (e.g. about 200eV per charge state for the SERSE source). The perspectives opened by the availability of MS-ECRIS source operating at 28GHz will be described along with some details on the proposed experimental programme, to be carried out in 2008 at GSI, Darmstadt.
