A system for spreading relativistic heavy ion beams into large uniform radiation fields has been developed. The charged particles passing through the system are deflected into azimuthally symmetric distributions which can then be superimposed to produce dose distributions as large as 30 cm in diameter with less than +/- 3.5% variation in uniformity.
一种用于将相对论重离子束扩展成大尺寸均匀辐射场的系统已被开发出来。穿过该系统的带电粒子被偏转到方位角对称分布，然后这些分布可以叠加起来，以产生直径达30厘米的剂量分布，均匀性变化小于±3.5%。
