An iterative method based on the use of approximate transfer operators, which was designed initially

Acceleration of the convergence of approximate operator iteration schemes is discussed. Algorithms based on both residual minimization and use of conjugate vector spaces are presented. It is shown that both give dramatic improvement, at very low computational cost, in the iterative solution of radiative transfer problems in the ...

The equations of thermal radiative transfer are time discretized in a semi-implicit manner, yielding a linear transport problem for each time step. The governing equation in this problem has the form of a neutron transport equation with fission but no scattering. Numerical methods are described, whose origins lie in neutron transport, and that have been ...

Means for measuring of LU-10 and LU-40 linear accelerators main electron radiation parameters, such as flux and density flux, charge in pulse, energy spectrum as well as transfer and electron energy transfer were metrologically investigated. Ranges of ind...
