Through the Laboratory for Ion Beam Interactions, the Division of Experimental Physics of the Rudjer Boskovic Institute (RBI) operates and maintains the Tandem Accelerators Facility (RBI-AF), that physically consists of the 6 MV Tandem Van de Graaff and 1 MV Tandetron accelerators, including associated beam lines and nine end stations used mainly for nuclear materials modification and analysis studies. The accelerators can deliver various ions with energies from 0.1 to tens MeVs.
Recently the facility has been increasingly used to study fusion energy related materials. In this work an overview of the RBI-AF applications to the fusion energy related research will be presented. This includes our activities on Ion Beam Analysis of fusion plasma facing materials [1,2] and the development and use of our Dual-Beam Irradiation Facility for Fusion Materials (Di-FU) [3-5]. The potential of the experimental setups will be demonstrated by presenting selected applications performed recently. Potential for further developments will also be discussed, including the need and availability of fundamental data necessary for analytical work [6,7].
