使用活化箔展开中子能谱是目前计划用于测量发电聚变反应堆第一壁中子能谱的主要技术。确定了当前箔片选择有效性的改进空间,并生成了一个程序来按程序选择箔片,以最大限度地提高展开过程的准确性。使用 Kullback-Leibler 散度来量化精度,发现由程序选择的一组箔片展开的光谱比文献中使用的一组箔片展开的光谱更准确。
Neutron spectrum unfolding using activation foils is currently the primary technique planned for measuring the neutron energy spectrum at the first wall of power-generating fusion reactors. Room for improvement in the effectiveness of current foil selection was identified, and a program produced to select foils procedurally in order to maximise the accuracy of the unfolding procedure. Using Kullback–Leibler Divergence to quantify the accuracy, the spectrum unfolded by the procedurally selected set of foils is found to be more accurate than the spectrum unfolded by a set of foils used in the literature.
