Plasma-based ion sources have ensured a constant boost of ions accelerators performances along the last four decades, and they are now crucial devices in several high-performances RIBs facilities worldwide. In the recent past the INFN-LNS Ion Sources team has developed a multi-diagnostics system allowing to characterize in-plasma electrons and ions densities and temperatures with unprecedented spatial and energy resolution. The results are of relevance for improving the performances of existing devices (boosting beam brightness and charge states) and for addressing the design of next-generation machines. ECR plasmas providing ion beams for particles accelerators are also attractive experimental setups for new studies about in-plasma nuclear decays. Lifetime variation as a function of the ions charge state was proposed to be studied in the frame of the PANDORA experiment now supported by the INFN 5th National Commission, which started in 2017. CosmoChronometers, or elements playing a role in the s-processes nucleosynthesis chains, can be investigated in a way complementary to/competitive with the ones already performed in storage rings.
