In order to cope with the limitation of long diffusion times affecting the extraction of short-lived isotopes, a lead bismuth eutectic (LBE) target loop equipped with a diffusion chamber has been proposed and tested offline at IPUL, Latvia, by E. Noah and co-workers. To validate the concept, a molten LBE loop is now in the design phase and will be prototyped and tested on-line at CERN-ISOLDE using a 1.4-GeV proton beam. Primary focus is given to the dimensioning of the diffusion chamber. The molten LBE concept inspired a new alternative route to produce 10¹³ 18Ne/s for the Beta Beams project, where a molten salt loop would be irradiated with 7 mA, 160-MeV proton beam. The concept has been validated by testing a molten fluoride salt static unit at CERN-ISOLDE using a 1.4-GeV proton beam. The investigation of the release and production of neon isotopes allowed the first measurement of the diffusion coefficient of this element in molten fluoride salts.
