New experimental data for production of (7)Be and (22,24)Na in deuteron irradiation of (nat)Mg and Al up to 50 MeV are presented. The induced activity, measured with HPGe spectroscopy, allows us to determine excitation functions of (nat)Mg(d,x) and (27)Al(d,x) reactions involved in the activation process with reference to (nat)Ti(d,x)(48)V monitor cross sections. A comparison with experimental literature values and results from updated theoretical codes is discussed. Thick target yields were derived from fits to our cross-sections and integrated personnel dose was calculated for different irradiation cycles and exposure scenarios around high power deuteron accelerator facilities.
本文给出了能量高达50 MeV的氘核辐照天然镁和铝产生(7)Be和(22,24)Na的新实验数据。利用高纯锗光谱仪测量的感生放射性,使我们能够参照天然钛(d,x)(48)V监测截面,确定活化过程中涉及的天然镁(d,x)和(27)铝(d,x)反应的激发函数。讨论了与实验文献值以及更新后的理论代码结果的比较。通过对我们的截面数据进行拟合得出厚靶产额,并针对高功率氘核加速器设施周围不同的辐照周期和照射场景计算了累积人员剂量。
