Project of the GDT-based steady-state experiment

In recent years, significant success in a plasma stabilization, heating and confinement in Gas Dynamic Trap (GDT) has been acheived. However, transition processes such as fast ions buildup, ion and electron temperature growth, etc., are still underway until the end of plasma heating. Thus, heating sources worktime (around 5 ms) is too short for plasma parameters to become stationary. In this work we propose a project of GDT-based stationary plasma experiment with pulse length long enough to finish all transition processes. The implemetation of the project will allow us to test GDT stabilization, heating and confinement methods to stationary conditions and to scale the methods to reactor-sized devices. Features of the project include a superconducting magnetic system with 15 T magnetic mirror field, 30 ms plasma pulse and mixed neutral particle and ECR heating. Results of numerical simulations of such experiment using DOL code are also presented.
