R&D Initi<strong>at</strong>ive on ion source :• Aim High On-line Efficiency for high charge St<strong>at</strong>es (q/A> 1/14)• Apparent Choice ECR ion sourceProblems‣ Poor vacuum (target evapor<strong>at</strong>ion) high q !!!‣ Neutron damage <strong>of</strong> permanent magnetsPossible solutionTwo ion source philosophyPrincipleTwo I.S. in cascade – EBPIS & ECR in our caseFirst I.S. provides q=1 + even in poor vacuumTransported to ECR <strong>at</strong> a distance to get high q(Better vacuum and acceptable n-flux)
