Abstract

An all-permanent magnetic electron cyclotron resonance (ECR) ion source LAPECR2 (Lanzhou all-permanent ECR ion source No.2) is being developed in Lanzhou. This ion source is believed to be a larger and heavier all-permanent magnetic ECR ion source in the world

which provides very high magnetic field inside the working volumn. This ion source will work on the IMP (Institute of Modern Physics) 320kV high voltage platform and provide intense high charge state ion beams for the successive experimental terminals. Many innovative methods have been adopted in the magnet design of LAPECR2. Due to the adoption of high remanence NdFeB material

optimum design and accurate calculation

the measured magnetic parameters are well up to the requirements of a high performance 14.5GHz ECR ion source. An off-axis rectangular wave-guide is used to feed 14.5GHz microwave inside the plasma chamber to heat the plasma. The adoption of off-axis RF feeding method will make the plasma more stable and the RF power feeding more efficient. Additionally

many tricky techniques such as the aluminum liner inside the plasma chamber

the biased-disc

the aluminum plasma electrode

the triode extraction system

the addition of auxiliary gas

etc

are employed to increase the production efficiency of high charge state ions.
