The equilibrium state of plasma puffs produced by a theta-pinch gun firing into an axial magnetic field has been studied theoretically. The plasma puffs are of finite length, with radially and axially dependent density gradients. This model, which is physically more realistic than an infinitely long puff, leads to a nonlinear partial differential equation for the density that is related to the generalized antisysmetric potential GASP type of equation. A Greens function method is described for converting the partial differential density equation into an iterative integral equation that appears more amenable to computer treatment. The iterated density thus becomes a functional of the trial density, which is the kernel of the integral equation. Author
