Numerical and experimental research of EMG-720 flux compression generator

Summary form only given, as follows. As the result of international cooperation, we previously developed and tested a 30 MJ generator which can be used to drive high-power stationary plasma radiation sources. For further improvement of the generator design and increase in output energy it is necessary to study in more detail the physical processes and to minimize the main loss mechanisms. In this paper we present experimental results and compare them with numerical simulations. It is shown that the main losses of magnetic flux are associated with nonlinear diffusion of the field in conductors and flux disruption at section joints. Expected performance parameters for an updated design with decreased flux losses are given.
