| Research Abstract |
We proposed a new inertial electrostatic confinement (IEC) fusion scheme which aims 'beam-beam' collisions between converging energetic ions with the aid of an internal ring-shaped magnetron ion source. Unlike linear dependence in the other existing IECs, experimental results showed fusion rate proportional to square of cathode grid current, which is encouraging for a drastic improvement in the fusion rate though it is also implied by experiments that a linear contribution from 'beam-target' collisions are still predominant under the present operating conditions. Also, a new scheme employing multistage electrode system was studied. The numerical simulations showed a possible drastic enhancement in the beam-beam fusion rate owing to an improved spherical symmetry of electrostatic potential distribution.
