Outline of Final Research Achievements

A high energy density plasma is generated from a matter irradiated by a high intensity laser pulse. Energy conversion is occurred in this high energy density plasma. For example, a part of laser energy can be converted into magnetic field energy by using a coil-shaped plasma. In this research, we have demonstrated generation of kilo-tesla-level magnetic field by using kilo-joule class high power laser and a capacitor-coil target. We have reduced divergence of relativistic election beams accelerated by high-intensity laser-plasma interactions by using laser-produced kilo-tesla magnetic field. We have developed an international research team to open a new frontier of plasma physics by combining strong magnetic field and high energy density plasma. Further progress in this new plasma physics can be expected even after the end of this project.
