Electron Cyclotron Resonance (ECR) ion source is regarded as the most efficient machine to produce stable multiple charge state ion beams. Because of the special characteristics

all-permanent magnet ECR ion sources have been widely adopted around the world to produce stable ion beams of multiple charge state with good repetition and high duty factor for compact research platforms and ion beam implanters. In this paper

all-permanent magnet ECR ion sources developed at IMP are presented

and typical parameters and performances are discussed. The high charge state source

LAPECR2

is mainly used to produce intense high charge state ion beams

and the LAPECR1 source is designed to produce intense ion beams of medium and low charge state. An improved LAPECR1-M is specially designed to produce heavy metal ion beams of low charge state. These ECR ion sources have been adopted by different experimental terminals at IMP and

with their nice performance

many experimental studies could be possible.
