用于放射治疗应用的重离子束的辐射场受到沿着组织中的穿透路径的核碎裂过程的显著影响,导致初级离子束通量的衰减和包括快中子的轻碎片的积聚。使用吸水剂作为组织等效束流停止靶,研究了GSI同步加速器SIS-18输送的200 MeV/u碳离子的二次碎片发射。利用快速闪烁探测器和飞行时间技术研究了从吸收体下游出射的快中子和带电粒子的能谱、角分布和产额。从产生的0.54个中子(E
The radiation field of heavy-ion beams used for radiotherapy applications is significantly affected by nuclear fragmentation processes along the penetration path in tissue, causing an attenuation of the primary ion beam flux and the build-up of light fragments including fast neutrons. The emission of secondary fragments from 200 MeV/u carbon ions delivered from the synchrotron SIS-18 at GSI was investigated using a water absorber as tissue-equivalent beam stopping target. Energy spectra, angular distributions and yields of fast neutrons and charged particles emerging from the absorber downstream were investigated by using fast scintillation detectors and time-of-flight techniques. From the resulting yield of 0.54 neutrons (E
