STABILITY CHARTS FOR THE IFMIF SRF-LINAC

Among the most recent projects, the IFMIF-EVEDA accelerators aim for the highest intensity, leading to a multi MW beam power at relatively low energy [1]. The concern for such accelerated beams is the predominance of the selffield energy upon the beam energy. In these conditions, the space charge effect is at its maximum, which triggers different nonlinear mechanisms implying emittance growth, halo formation and finally, particle lost. In this proceeding we show the stability charts constructed for the IFMIF SRF-Linac, with which are identified the collective space charge resonances responsible for transverse-longitudin al emittance exchange and emittance growth.
