Worldwide ECR ion source development has stepped into the era of 4th generation that needs to solve series of technical and physics problems. Nevertheless, the 3rd generation ECR ion sources are still the most advanced machines to produce very intense highly charged ion beams, such as 0.66 emA Ca¹²⁺, 1.4 emA Ar¹²⁺, 0.8 emA Xe²⁷⁺, 16.7 euA Xe⁴²⁺, 0.68 emA Bi³¹⁺, 3 euA Bi⁵⁶⁺, 400 euA U³⁴⁺ and so on. These results can obviously improve the existing heavy ion facilities performance and have fundamental impact to the development of future facilities as well. This paper will review the worldwide achievements on high performance ECR ion source development in recent years. PB - JACoW Publishing CP - Geneva, Switzerland ER -
