rare isotopes with GSI ECR Ion Sources ECR ion sources (ECRIS) of CAPRICE-type, working at 14.5 GHz, are in use at the High Charge State Injector (HLI) of the accelerator facility at GSI for beam production [...] the magnetic field, several assumptions used for beam transport issues are not valid any more: for example, two-dimensional emittance does not stay constant in every case; the six dimensional phase space
