Since a few years, a novel approach to perform multi-turn extraction is under study at the CERN PS machine. It is based on beam splitting in the horizontal phase space by means of adiabatic capture of charged particles into stable islands. This manipulation allows generating an extracted beam nicely matching the phase space of the receiving machine with virtually no losses. The proposed technique is thus an ideal candidate to replace the extraction mode called Continuous Transfer, routinely used to deliver the proton beam to the SPS for the fixed-target Physics programme, and it is a crucial development for the future scheme to generate a high-intensity proton beam for CNGS. The principle of the Continuous Transfer as well as of the novel multi-turn extraction will be briefly reviewed, their performance compared, and the experimental results of past years summarised. The main focus will be on the experimental findings obtained in summer 2004. Also, an outline of possible scenarios to implement the proposed extraction scheme will be given.
