Abstract

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 eµA of C<superscript>5+</superscript> ion beam should be extracted from the ion source, and the beam emittance better than 75 7r*mm*mrad. In recent commissioning, about 120 eµA of C<superscript>5+</superscript> ion beam was got when work gas was CH<subscript>4</subscript> while about 262 eµA of C<superscript>5+</superscript> ion beam was obtained when work gas was C<subscript>2</subscript>H<subscript>2</subscript> 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. [ABSTRACT FROM AUTHOR]
