为了提高GANIL重离子束撞击厚靶产生的放射性同位素的收集效率，设计了一种名为SISSi的装置，将这些束聚焦在直径为0.4 mm的光斑上。考虑到即将到来的加速器的修改，这将使束流强度提高15倍，以及对于目前的情况，必须设计一种靶，以可靠地耗散由重离子沉积在如此小的区域上的高功率。磁和低温环境，沿着辐射和安全问题，是下面描述的设计中的严重限制。给出了初步的实验结果。
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.
