New Method of lon Injection into Helical Device with the Use of the Helical Ripple Loss Cone

New physical mechanism of the ion injection into the helical device is proposed in which the natural helical loss cone is used. We have shown that the ions with the energy W = 5 keV and small pitch-angle VllV = 0.3 injected into the helical magnetic trap from outside of the confinement volume can penetrate in the core of plasma. The particles with the transit orbits can reach the center of the confinement volume. In addition we have clarified the possibility of generating the strong positive radial electric field in the bulk plasma within the framework of neoclassical theory.
