摘要:公开了小型粒子选择及准直装置,用于以所需要的能谱传递离子束。这些装置使用激光加速离子治疗系统,其中,初始离子具有宽阔的能量和角分布。超导电磁体系统产生所需要的磁场构造,从而以不同的能量和发出角度散布粒子用于颗粒选择。在有磁场情况下,离子传送仿真显示出,所选择的离子在通过磁场之后成功地重新聚集在束轴上。还使用用于放射疗法应用的激光加速离子束的蒙特卡洛仿真,来提供剂量分布。

主权项:1. 一种离子选择系统,包括:准直装置,能对包括多个高能量多能正离子的激光加速高能量多能离子束进行校准;第一磁场源,能够根据所述高能量多能正离子的能级,空间地分离所述高能量多能正离子;孔,能够调制该空间分离的高能量多能正离子;以及第二磁场源,能够将经过调制的高能量多能正离子重组;其中,第一和第二磁场源是能够提供大约0.1和大约30特斯拉之间的磁场的超导电磁体。
