	At INFN-LNS the commissioning of the AISHa superconducting ECRIS started in November 2016. Highly charged ion beams with low ripple, high stability and high reproducibility are the most important features for the ongoing commissioning. In this work, we will show the preliminary results of a parametric study on the extracted current/beam in order to minimize the emittance and increase the brightness taking advantage by its hybrid magnetic system and by a fine frequency tuning system.

	Funding: This work was supported by the U.S. Department of Energy and National Aeronautics and Space Administration. Generation of highly-charged heavy ions such as fully stripped C⁶⁺ of more than hundreds mA of beam current can be possible only with a laser ablation ion source (LIS). Heavy ions are produced from a solid target irradiated by a pulsed high power laser. Recent study showed that only sub-micron range of surface layer contributes for the generation of highly-charged heavy ions. In this paper, we experimentally investigated the difference of the performance of highly-charged carbon ion production from graphite targets of different thickness (25, 70, 254, and 3000 'm) to seek the possibility of a rolled target to overcome the limitation of a target lifetime.

	Funding: This work was supported by the U.S. Department of Energy and National Aeronautics and Space Administration. We are studying a laser ion source (LIS) for a high average beam power heavy ion beam production. A LIS is the most intense source of pulsed highly-charged ions using a laser ablation scheme. By increasing the repetition rate, a LIS based heavy ion beam would approach the average beam power based on a low beam current and continuous beam regime. In addition, a high-repetition-rate LIS can be used as a heavy ion source for a medical accelerator with spot scanning technique. This paper will describe the requirements to realize the high repetition rate operation.
