| Outline of Final Research Achievements |
We proposed and studied the dynamic control of a laser ablation plasma using a magnetic nozzle. This plasma control method can be one of fundamental technologies of heavy ion inertial fusion, which is expected as a future energy resource. A pulsed magnetic field was induced by a coil located near the metallic laser target, and the behavior of a laser ablation plasma, which was generated in the magnetic field having a nozzle-like structure, was examined by plasma spectroscopy and ion flux measurement. We clarified that the behavior not only of plasma ions but also of neutral atoms were affected by the induced magnetic field. Meanwhile, our investigation did not go far enough to confirm the acceleration of plasma particles or the improvement of the directivity of them.
