Popis: Radioactive ion implantation allows non‐contacting, online wear measurements with sub micrometric sensitivity to be performed, by monitoring the removed and/or residual activity on parts subject to wear. Comparative studies of different materials, including those who exhibit a low resistance to radiation damage, can be easily performed by means of this technique. A project has started at the TTT3 tandem of the University “Federico II” in Naples, Italy, in order to exploit such technique using a 7Be ion beam, that was developed to study the astrophysical important reaction 7Be(p,γ)8B. The 7Be ion beam is produced using a ion sputter source and accelerated to an energy up to 8.0 MeV. A novel setup allows control of the implanted ion depth distribution, and is a crucial point for the application of this technique. The 7Be ion beam production and implantation procedures are discussed. Finally, the results of some test measurements are presented.
