  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.

  In order to investigate the ion optical parameters of the beam line of RIKEN 28 GHz SC-ECR ion source into the new heavy ion linac (RILAC II), we measured the emittance of the heavy ion beams form RIKEN 28 GHz SC-ECR ion source. In the test experiments, we observed that the emittance of the U35+ beam was ~100 π·mm·mrad (4 rms emittance), which is smaller than the acceptance of the accelerator (~160 π·mm·mrad). The emittance with 28 GHz was almost same as that with 18 GHz and independent on the injected RF power (1~2 kW). The size of emittance increased with decreasing the charge state. We also measured the emittance of U and oxygen ions under the same condition. In this experiment we observed that the emittance of oxygen ions was always larger than the U ion beam for same M/q. In this contribution, we report the experimental results for emittance measurement of highly charged U, Xe and O ions from RIKEN 28 GHz SC-ECR ion source in detail.
