Plasma Excitation

Several modifications of the direct current plasma jet have resulted in significantly enhanced analysis capabilities. Reducing the electrode angle, decreasing the aerosol chimney size, and operating in a diffuse mode with helium have provided improved stability, sensitivity, freedom from interferences, and detection limits. While the actual mechanism of the helium enhancement is not clear, no direct evidence was found which supports participation in the excitation step. Rather, improved desolvation, vaporization and possibly sample introduction result from the thermal conductivity of helium being much greater than that of argon.

The SPES project at Laboratori di Legnaro of INFN (Italy) is concentrating on the production of neutron-rich radioactive nuclei for nuclear physics experiments using uranium fission at a rate of 1013 fission/s. The emphasis on neutron-rich isotopes is justified by the fact that this vast territory has been little explored. The Radioactive Ion Beam (RIB) will be produced by the ISOL technique using proton induced fission on a direct target of UCx. The most critical element of the SPES project is the Multi-Foil Direct Target. Up to the present time, the proposed target represents an innovation in terms of its capability to sustain the primary beam power. This talk will present the status of the project financed by INFN, which is actually in the construction phase at Legnaro. In particular, developments related to the target and the ion-source activities using the surface ion source, plasma ion source, and laser ion source techniques will be reported.
