Magnetically driven plasma guns that are inserted around a flux conserver at definite angular intervals are considered. The creation and the control of plasma channels are examined. By means of the hybrid model developed, both a system analysis of the Alternative Spherical Tokamak (AST) and relevant computational experiments have been carried out. In addition, by using the results obtained from the numerical scheme, the complex non-inductive current drive mechanisms of bootstrap and helicity injection in the AST system are discussed in detail.
