Invariant Imbedding and Neutron Transport Theory IV-Generalized Transport Theory

Neutron Transport Theory and Simulation

Devoted to describing neutron movement in media and the corresponding laws, neutron transport theory is the research basis for transmutation and activation, radiation damage to materials, radiation dose, and biological safety, among other topics. There are two methods for neutron transport calculation: the Monte Carlo method (also called the probabilistic method or the stochastic method) and th...

ESTIMATION OF RADIATION LOSS FROM STELLARATORS USING NEOCLASSICAL TRANSPORT THEORY

The radiation power loss from a magnetically confined plasma in a stellarator has been calculated using neoclassical particle and energy fluxes in an energy balance equation. We could obtain a power loss of about 34% of the total input power by numerical calculation. This fraction of the power loss has been found to be in good agreement with the experimentally measured values of 30-40% for...

The Quantum Statistical Mechanical Theory of Transport Processes

A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.
