摘要：

A high charge state all permanent Electron Cyclotron Resonance ion source, Lanzhou All Permanent ECR ion source no. 3-LAPECR3, has been successfully built at IMP in 2012, which will serve as the ion injector of the Heavy Ion Medical Machine (HIMM) project. As a commercial device, LAPECR3 features a compact structure, small size, and low cost. According to HIMM scenario more than 100 e mu A of C5+ ion beam should be extracted from the ion source, and the beam emittance better than 75 pi*mm*mrad. In recent commissioning, about 120 e mu A of C5+ ion beam was got when work gas was CH4 while about 262 e mu A of C5+ ion beam was obtained when work gas was C2H2 gas. The design and construction of the ion source and its low-energy transportation beam line, and the preliminary commissioning results will be presented in detail in this paper.
