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.

Since the development of inductive heating oven in 2019 [1], several intense highly charged metallic ion beams have been produced for different requirements at IMP (Institute of Modern Physics). According to the material characteristics, we used different forms of metal materials, including metal elements (Cr, Mn, Ni, Fe), oxides (UO₂), fluoride or iodide (ZrF₄, SrF₂, CsI), etc. Detail experiments setup and testing results will be presented in this contribution.

Highly charged ion beams have wide applications in fundamental sciences such as nuclear physics and atomic and molecular physics, as well as in applied industries including heavy ion cancer therapy and semiconductor processing. The Electron Cyclotron Resonance (ECR) ion source is one of the most effective devices for producing highly charged ion beams. Based on the requirement for a relatively simple structure and high performance ECR ion source, a Hybrid superconducting Electron Cyclotron Resonance ion source Advanced in Lanzhou (HECRAL) has been designed and constructed at the Institute of Modern Physics (IMP). The magnetic confinement of the ion source is realized by the axial mirror field provided by four superconducting solenoids while the radial hexapole magnetic field supplied by non-Halbach hexapole permanent magnet. The axial injection and extraction magnetic fields reach 3.4 T and 1.7 T, respectively. The radial field at the plasma chamber wall of a 100 mm inner diameter is above 1.4 T. This paper will present a detailed magnet design. The ion source was commissioned and operated at a frequency of 18 GHz with 3 kW power, approaching the performance of the Superconducting Electron Cyclotron Resonance ion source with Advanced design in Lanzhou (SECRAL) operating at the same frequency. Several high intensity high charge state ion beams have been produced, such as 723 eμA O⁷⁺, 70 eμA Ar¹⁶⁺, 95 eμA Kr²⁶⁺, 21 eμA Xe³⁵⁺, 120 eμA Bi³³⁺, and 88 eμA U³⁷⁺, and so on.

An all-permanent magnet electron cyclotron resonance ion source-LAPECR3 (Lanzhou All Permanent magnet Electron Cyclotron Resonance ion source No.3) had been developed as the C⁵⁺ ion beam injector of Heavy Ion Medical Machine (HIMM) accelerator facility since 2009 in China. The first HIMM demo facility was built in Wuwei city in 2015, which had been officially licensed to treat patients in early 2020. The facility has been proven to be very effective, and more than 1000 patients have been treated so far. In order to prevent ion source failure, each facility employs two identical LAPECR3 ion sources to supply C⁵⁺ beam. At present, there are eight HIMM facilities under construction or in operation, and more than 16 LAPECR3 ion sources have been built. In order to improve the performance of the ion source for long term operation, some techniques were employed to optimize source performance and to avoid the damage of key equipment. This paper will introduce the operation status of LAPECR ion sources at these HIMM facilities and present the latest results of carbon beam production.
