Beam Extraction Studies for the Proposed Superconducting Cyclotron at the University of Milan
The preliminary extraction scheme described here does not seem, in principle, to offer any major obstacles. Further development should go towards: i) minimizing the problem of adapting the contour of deflectors to the trajectories of different ions, given the rather different orbits scalloping at high and low magnetic fields. ii) minimize the range of movements required for the extraction elements. iii) verify the possihility of insertiont of a third deflector, iiii) verify the possibility of an essentially constant,fixed, gradient for the magnetic channel, in which case a passive channel could be adopted. Work on these issues is in progress, and will be completed as soon as magnetic field data from the 1:6 scale model are available.
