Integrated Transport Code Sytem for Multicomponent High-ß Plasmas in the Gas Dynamic Trap

The Budker Institute Novosibirsk made the proposal for a high-power 14 MeV neutron source on the base of a gas dynamic trap (GDT). The GDT is an axisymmetric open trap with a high mirror ratio confining a collisional plasma. To be able to calculate the dynamics of the particle fields appearing inside the existing experimental GDT device of the Budker Institute, and later, inside the neutron source an Integrated Transport Code System (ITCS) is under development. It is to consider the full dependencies of the transport phenomena on space, time, energy and angle variables as well as the interactions between the fields. The paper briefly describes the theoretical and numerical models of the code system and illustrates its first application to calculate the particle fields inside the experimental GDT facility.
