Charged by the existing operation facility HIRFL and HIAF one of the next generation heavy ion facilities under construction, high intensity high-charge state heavy ion beams production is in the high priority of research and development. For this purpose, several high performance ECR ion sources have been successively developed and put in routine operation. The recently developed FECR or the First 4th generation ECR ion source has employed the cutting-edge technologies for the development of a hybrid superconducting magnet using Nb₃Sn and NbTi superconductors. Operating at 28-45 GHz, FECR will give its first plasma and intense beam production. Other than ion sources development, new technologies development and new insights into high performance ECR ion source have led to increasingly ion beam intensities increase in both cw or pulsed modes. In this talk, high performance ion source development will be presented. A general review of the recent high intensity ion beam production progress at IMP and the routine operation for heavy ion accelerators will be made.

Intense pulsed uranium ion beam production is essential for heavy ion accelerators (especially for synchrotrons) in operation and those under construction. Although metallic beam production is tricky, based on our earlier study, intense uranium beams can be expected when operating a electron cyclotron resonance (ECR) ion source especially in afterglow mode. In this study, we aim to produce intense uranium beams with LECR4 and SECRAL-II (Superconducting ECR ion source with Advanced design in Lanzhou No. II) ion sources in afterglow modes. The experimental results will be reported in this presentation.
