The high power target system for SISSI, an intense source of secondary ions
E. Baron1, J. Gillet1, M. Ozille1

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.
