• 論文の詳細を見る

• A method is presented for generating a high magnetic field using a CO_2 laser pulse. The magnetic field, current and voltage in a one-turn coil were measured as functions of the gap width, where the high voltage was induced by laser irradiation at a fixed intensity of 1.3 × 10^<14> W/cm^2. These results could be explained on the basis of lateral transport by hot-electron E × B motion and an expansion of the critical density plasma in the gap. The maximum magnetic fields are determined and limited by the filling time of the gap with a critical-density plasma. In order to obtain higher magnetic fields, we tested a cylinder-type one-turn coil attached to the optimized gap. The highest magnetic field observed was 400 T.
