Abstract An accelerator system is described which is in use for radiation damage studies, analytical (RBS) and structural (channeling) measurements, and high energy ion implantation. An important feature of the system is its high current capability for radiation damage. The injector is equipped with three ion sources and is operated at 80 kV to permit high intensity ion beam currents to be accelerated. A parallel fed voltage multiplier located within SF 6 gas of 8.3 bar pressure produces stable voltages in the range of 0.400 to 1.700 MV. The beam is transported by a switching magnet to four target stations.
