This paper describes the latest developments in neutron sources developed for fast neutron therapy. Two approaches have been taken using cyclotrons and D-T generators. For cyclotrons the proton on beryllium reaction is now preferred since smaller cyclotrons for a given neutron penetration can be used. Optimization of target thickness and filtration is necessary to obtain maximum beam penetration. D-T generators have been developed either as multi-beam accelerators or using ultrapure techniques to obtain maximum neutron output.
本文介绍了为快中子治疗开发的中子源的最新进展。采用了两种方法，即使用回旋加速器和D-T发生器。对于回旋加速器，现在更倾向于质子与铍的反应，因为对于给定的中子穿透能力，可以使用更小的回旋加速器。为了获得最大的束流穿透能力，需要对靶厚度和过滤进行优化。D-T发生器已被开发为多束加速器或使用超纯技术以获得最大的中子输出。
