  A 70 MeV H cyclotron commercially available for medical isotope production will be used as an ISOL driver for rare isotope science project in Korea. The cyclotron is scheduled to be installed in 2021 for beam commissioning in the following year. In fact the building to house the cyclotron is currently almost complete so that the cyclotron system newly contracted needs to fit into the existing building, which brings some challenges in equipment installation and adaptation to utilities. Two beam lines to transport high-current proton beams into ISOL targets have been designed and are described along with other issues associated with the interface of the ISOL system.

  ECR Ion Sources are deemed to be among the most performing ion sources feeding particle accelerators, cyclotrons in particular. Improvements of their performances strictly depend on the knowledge of plasma physics in compact magnetic traps. The paper will comment on the results obtained by the INFN-LNS team and international collaborators by means of a multi-diagnostics setup able to monitor the evolution in space and time of several plasma parameters, simultaneously with beam extraction and analysis in the LEBT, in single vs. double frequency operations, including the RF power and magnetic field scalings, and exploring regimes dominated by plasma turbulence. The results are relevant for the operations of existing ion sources and for the design of new ones. Compact magnetic traps fashioned in a similar way of ECRISs can be considered as an experimental environment by itself: we are exploring this opportunity relying to the in-plasma measurements of radionuclides lifetimes (in particular, beta-decaying elements): CosmoChronometers or nuclei involved in the s-process nucleosynthesis are among the case studies, opening new perspectives in the nuclear astrophysics field.
