	Up to now, eighteen Target Ion Source Systems (TISS) have been built and used for the production of radioactive ion beams on SPIRAL I facility, based on the Isotope Separator On Line method. The TISS's are composed of a helium or argon target and of the fully permanent magnet ECRIS Nanogan III. After irradiation and a period of two years for radioactive decay, the irradiated TISS is dismounted and if its magnetic field is still suitable, the magnetic systems is renewed and associated to a new target. Thereby thirty two runs have been performed using new or renewed TISS's. Sometimes, the measurement of the magnetic field after irradiation shows a degradation of the permanent magnet. The feed-back of our experience is reported here. In a second part, we present the progress on the NanoNaKE setup, which aims to extend the radioactive ion beams on SPIRAL I to the alkali elements, by associating a surface ion source to the Nanogan III ECRIS via a compact 1+ ion beam line. The main issues and difficulties are discussed and the preliminary solutions are described.
