Formation of a High Energy Density Field Reversed Configuration

Formation of a compact toroid (CT) or field reversed configuration (FRC) [1-2] with a maximum input of energy and the capture of the magnetic field into plasma is an important scientific and technical challenge. The proposed method of formation is similar to the formation of FRC based on $\theta $-pinch [1], but has some differences, which will be described below. One of the main CT formation problems is the low level of the captured magnetic flux. A study of compact torus formation with a longitudinal current was done [3]. This method of formation has not been used before, and was tested for the first time. Experiments showed that this method can significantly increase the energy input into plasma.\\[4pt] [1] R.H.
