Description
FECR or the First 4th generation ECR ion source is
under development at Institute of Modern Physics
(IMP) since 2015. This ion source is aiming to extract
intense highly charged heavy ion beams in the order
of emA from the dense plasma heated with 45 GHz
microwave power. To provide effective magnetic
confinement to the 45 GHz ECR plasma, a state of
the art Nb3Sn magnet with min-B configuration is a
straightforward technical path. As there is no much
precedent references, it has to be designed,
prototyped at IMP through in-house development.
Meanwhile, other physics and technical challenges to
a 4th generation ECR ion source are also tackled at
IMP to find feasible solutions. This paper will give a
brief review of the critical issues in the development
of FECR ion source. A detailed report on the status of
FECR prototype magnet development will be
presented.
