A hollow intense heavy ion beam with an annular focal spot has many important applications. The Gesellschaft für Schwerionenforschung, Darmstadt is planning to develop a radio frequency wobbler that will rotate the beam at extremely high frequencies and thus create an annular (ring shaped) focal spot. In this paper, we present an analytical model that determines the minimum rotation frequency of the wobbler in order to achieve a high degree of irradiation symmetry (an asymmetry of a few percent) of the target. Estimates for a typical heavy ion imploded target are also presented.
具有环形焦斑的空心强重离子束有许多重要应用。德国达姆施塔特重离子研究中心正计划研制一种射频摆动器，它将使束流以极高频率旋转，从而产生一个环形（环状）焦斑。在本文中，我们提出了一个分析模型，该模型确定了摆动器的最小旋转频率，以实现靶材的高度辐照对称性（几%的不对称性）。文中还给出了典型重离子内爆靶材的估算结果。
