Algorithms were developed to solve the problem of radiation transport based on the method of long characteristics, taking into account its optimization in the framework of the quasi-one-dimensional approximation used to study the axisymmetric flows of the ionizing gas in coaxial channels of plasma accelerators. The optimization of calculations of the integral radiation parameters allowed to significantly reduce the calculation time in comparison with three-dimensional model of radiation transport. Calculations of the radiation energy density and the radiation energy flux density, based on various methods, have shown that new algorithms provide high-quality solution of the radiation transport problem.
