Since 2010 the GTS-LHC source delivers lead ions for heavy ion physics at the LHC. Several modifications allowed improving the source reliability and the beam stability. The attempts to improve the beam intensity were less successful. The different modifications and actual performance figures will be presented in this paper. In addition to the heavy ion physics program of the LHC new ion species will be requested for different experiments in the future. The fixed target experiment NA61 requires primary Argon and Xenon beams. And a future radio-medical facility asks for light ions in the range Helium to Neon. Approaches to prepare these beams and to modify the ion injector towards a light ion front end are presented.

At iThemba Laboratory for Accelerator Based Sciences a copy of the so-called Grenoble Test Source (GTS) for the production of highly charged ions is installed. The source in combination with the K-200 cyclotron delivers high energy, high intensity beams for nuclear physics experiments. In this paper we present beam experiments with the GTS at iThemba LABS, in which the results of CW, pulsed and afterglow operation for different bias disc voltages and positions are compared.
