The paper considers two algorithms for calculating the neutron yield of the Globus-M2 tokamak for the case of anisotropic ion distribution functions. Such calculations are necessary to estimate the flux of neutrons produced as a result of the interaction between fast particles (deuterons) arising from the neutral beam injection. The first algorithm is the calculation of a six-dimensional integral in the velocity space, and the second uses the expansion of the ion distribution function in terms of Legendre polynomials, which allows one to reduce the dimension of integration. The advantages and disadvantages of each of the algorithms are discussed and the results obtained using them are compared.
