摘要

利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。确定了当前箔选择有效性的改进空间，并编制了程序来选择箔，以便最大限度地提高展开程序的准确性。使用Kullback-Leibler散度来量化精度，发现由程序选择的一组箔展开的光谱比文献中使用的一组箔展开的光谱更准确。

Optimising Foil Selection for Neutron Activation Systems

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.

期刊介绍： The Journal of Fusion Energy features original research contributions and review papers examining and the development and enhancing the knowledge base of thermonuclear fusion as a potential power source. It is designed to serve as a journal of record for the publication of original research results in fundamental and applied physics, applied science and technological development. The journal publishes qualified papers based on peer reviews. This journal also provides a forum for discussing broader policies and strategies that have played, and will continue to play, a crucial role in fusion programs. In keeping with this theme, readers will find articles covering an array of important matters concerning strategy and program direction.
