1 GANIL - Grand Accélérateur National d'Ions Lourds

In order to increase the collection efficiency of radioactive isotopes produced by the GANIL heavy ion beams impinging onto thick targets, a device named SISSi was designed to focus these beams on a 0.4 mm diameter spot. In view of the upcoming modification of the accelerator which will boost the beam intensities by a factor of 15, as well as for the present situation, a target had to be designed to reliably dissipate the high power deposited by the heavy ions on such a small area. The magnetic and cryogenic environment, along with the radiation and safety problems, were severe constraints in the design described below. Preliminary experimental results are given.
