The heavy ion irradiation facility at CYCLONE - a dedicated SEE beam line

After a two years evaluation and assessment period of the CYClotron of LOuvain la NEuve (CYCLONE) usability for heavy ion SEE testing, the European Space Agency has now initiated the set-up of a permanent beam line dedicated for SEE testing. This paper describes the CYCLONE accelerator, the beam line used so far, presents some experimental results which are compared with data obtained at the Tandem accelerator at Brookhaven National Laboratory (BNL) and details present and future developments.
