High Energy Density Science<\/h3>\n<h4>Laser Astrophysics\u00a0(Representative: Masahiro Hoshino (Professor), Contact scientist: Youichi Sakawa (Associate Professor))<\/h4>\n<p align=\"left\">Utilizing high-temperature, high-energy-density, and ultra-high flow-velocity plasmas observed only in the Universe, we aim to understand plasma physics and astrophysics using large-energy\/high-power lasers in the laboratories. Many astrophysical phenomena such as collisionless shock generation, magnetic reconnection, plasma-jet collimation and instabilities are related to explosion and instantaneous energy-release. We simulate these phenomena in the laboratory using pulse lasers. Relativistic laser astrophysics, such as electron-positron plasma generation and particle acceleration using high-intensity lasers, is also an important topic of interest.<\/p>\n<p align=\"left\">We also study theory and simulation on these topics shown above.<\/p>\n<p align=\"left\">(a)Laser Plasma Astrophysics: Experiment<br \/>\n(b) Laser Plasma Astrophysics: Theory\/Simulation<\/p>\n<h4>High Pressure \/ Laser Earth &amp; Planetary Science \u00a0(Representative: Toshimori Sekine (Professor), Contact scientist: Keisuke Shigemori (Professor))<\/h4>\n<p align=\"left\">High-energy lasers can generate extreme pressure and temperature conditions beyond the limit of traditional high-pressure apparatus such as large volume press, diamond anvil cell, and light-gas gun. It can be applied to study physical properties of the Earth and planetary materials, as well as various impact phenomena of planetary surfaces. We investigate the EOS of shocked materials, high-pressure phase transitions, physical properties of solids and liquids, deformation and breaking mechanism, acceleration and impact process, degassing and vaporization of shocked materials, synthesis and chemical reaction of prebiotic materials, gravitational instability simulating core formation, and so on, using newly developed in-situ measurements and recovery methods to clarify the formation process, internal structure and evolution of the Earth and other planets including Super-Earths.<\/p>\n<p align=\"left\">(a) In-situ Measurements of Shock-compressed Materials<br \/>\n(b) High-speed Impact and Recovery of the Sample<\/p>\n<h4>High Magnetic Field Science\u00a0(Representative: Joao Santos (Dr.), Contact scientist: Shinsuke Fujioka (Professor))<\/h4>\n<p align=\"left\">The combination of laser-produced strong magnetic field and high-energy-density plasma can open a novel field of plasma physics. The objectives of this subject are to develop an experimental platform utilizing 100 kT and to build domestic and international networks. We welcome your proposals to develop novel generation schemes of strong magnetic field, to control generation and transport of laser-accelerated beams, to understand high-energy-density-plasma physics under the strong magnetic field, and to apply the strong magnetic field to ICF and MCF plasmas. We also welcome interdisciplinary proposals, for example, plasma propulsion with strong magnetic field and x-ray spectroscopy under strong magnetic field for x-ray astronomy applications.<\/p>\n<h4>Quantum Beam Science (Representative: Takehito Hayakawa, Contact scientist: Akifumi Yogo (Associate Professor))<\/h4>\n<p>Laser-produced plasma generates high energy particles, including ions, electrons, neutrons, and intense radiative emission ranging from extreme ultra violet (EUV) to gamma-ray.
