The design of radioactive ion production systems by Isotope Separator On Line method requires knowledge of diffusion features of atoms out of solids. With respect to the large number of possible diffusing atoms in target material, it is often difficult to find the right information in the literature, and inter-comparisons are often difficult due to differences in the experimental techniques and conditions. The TARGISOL European collaboration has the aim to study the relevant variables governing the release of radioactive elements from targets, to produce new radioactive ion beams and to build a data base which can facilitate the design of radioactive ion beam setups. The role of GANIL in this collaboration is to develop and produce new radioactive beams and provide new diffusion coefficient data. For this purpose, GANIL has designed a new system which removes part of the problems of comparing data. The approach is systematic measurements of release properties from several targets using the same process, the same apparatus and during the same experiment. This new approach will be presented with the set-up and the characterizing tests of the apparatus. Results of two experimental periods will be presented at this conference
