摘要

文章探讨了一种利用中子层析成像技术确定聚变反应堆第一层壁氚表面分布的现场方法。该方法包括在氚饱和后形成脉冲周期性加速氘核通量轰击所研究的第一堆壁表面，根据 T (d, n)4He 反应生成快中子场，测量给定空间点的中子通量，以及根据测量数据重建空间氚分布。根据逆弗雷德霍姆问题的近似解，提出了这种重建的算法。

Surface distribution of tritium in the first wall of a fusion reactor according to the data of neutron measurements

The article considers an in-situ method potential for establishing the surface distribution of tritium in the first wall of a fusion reactor using neutron tomography. The method includes the formation of a pulse-periodic flux of accelerated deuterons bombarding the studied surface of the first reactor wall following its saturation with tritium, generation of a fast neutron field according to T (d, n)⁴He reaction, measurement of neutron fluence at given spatial points, and reconstruction of the spatial tritium distribution according to measurement data. An algorithm for such a reconstruction is presented based on an approximate solution to the inverse Fredholm problem.
