| Abstract: | A new type of ambipolar trap is proposed, where a minimum-B magnetic field is used to confine the particles radially and to provide plasma macroscopic stability. The particles are confined axially by creating the plug potentials at both end-mirror cells of the ambipolar trap. The plug potential is produced by only electron cyclotron resonance heating, the mechanism of which is proposed. |
