Abstract

Two algorithms for calculating the neutron yield of the Globus-M2 tokamak are considered for the case of anisotropic ion velocity distribution functions. Such calculations are necessary for estimating the neutron flux produced as a result of the interaction between fast particles (deuterons) arising from the injection of a high-energy atomic beam. The first algorithm comprises the calculation of the six-dimensional integral in the velocity space, and the second uses the expansion of the ion distribution function in Legendre polynomials, which allows one to reduce the dimension of integration. The results obtained using these algorithms are compared, and the advantages and disadvantages of both algorithms are discussed.

计算中子注入时高能原子的离子速度分布函数的各向异性，从而计算Globus-M2托卡马克的中子产率。

摘要

对于各向异性离子速度分布函数，考虑了两种计算Globus-M2托卡马克中子产率的算法。这样的计算对于估算由于注入高能原子束而产生的快速粒子（氘核）之间的相互作用而产生的中子通量是必要的。第一种算法包括计算速度空间中的六维积分，第二种算法使用勒让德多项式中离子分布函数的展开，从而可以减小积分的维数。比较了使用这些算法获得的结果，并讨论了两种算法的优缺点。
