The world biggest all permanent magnet Electron Cyclotron Resonance (ECR) ion source with the highest magnetic field has been successfully designed and fabricated at IMP

which is named LAPECR2 (Lanzhou All Permanent magnet ECR ion source No. 2). After being assembled

LAPECR2 source was situated on the 320 kV high voltage platform at IMP and connected to the successive ion beam transmission beam line. The first plasma of LAPECR2 was obtained in July 2005 with 14.5 GHz microwave power injection

and an intense mixing ion beam had also been extracted at the same time. Presently

the on-line test of the source LAPECR2 with the successive experimental beam line has been accomplished

and many kinds of intense high charge state ion beams have been detected at the experimental terminals. After a detail introduction of the ion source structure

the main characteristics are given. Then the preliminary results of the source at 14.5 GHz rf power injection are presented. After that

the on-line tuning results with the experimental beam line are presented and some corresponding discussion is also given. The aspects that affect the performances of the beam line are tentatively investigated in this paper.
