    Power Electronics and Electrical Energy Area

    Professor ISE Toshifumi   Associate Professor MIURA Yushi
    Power electronics is the key technology for future power systems with low environmental loads and efficient use of energy resources. Power technologies become to be closer and more friendly to people like mobile phones. This concept is called as ""Ubiquitous power"". Our laboratory members are working and studying for developing basic technologies based on power electronics and applied superconductivity for future power systems considering environmental problems and energy resource problems.
    • Future power delivery systems including many distributed generations with low environmental loads
    • Distributed generations and energy storages with high efficiency power conditioning systems
    • Application of next generation power semiconductor devices such as GaN
    • Power system controlling devices using power electronics

    Intelligent System Area

    Professor TAKAI Shigemasa   Associate Professor MIYAMOTO Toshiyuki   Assistant Professor HAYASHI Naoki
    Most existing systems consist of several components that operate concurrently. Such systems are called concurrent systems. We are interested in developing efficient techniques for verification, control, and optimization of concurrent systems using mathematical models. Our recent research topics include analysis and control of concurrent systems, control and scheduling of intelligent vehicles, modeling and verification of distributed software, and so on.

    Power Device Area

    Professor FUNAKI Tsuyoshi   Associate Professor SUGIHARA Hideharu   Assistant Professor IBUCHI Takaaki
    The research works in our laboratory aim at energy saving, miniaturization, and improving performance of power conversion system, which are based on the simulated analysis with evaluating and modeling of loss in power conversion circuit, electromagnetic noise caused by switching operation, and temperature rise by dissipated loss. To this end, the elements of switching device, passive component, and JISSO technology, which are used in the power conversion system, are evaluated and expanded to build system model.

    Systems Analysis and Optimization Area

    Associate Professor TATSUMI Keiji   Assistant Professor KUSUNOKI Yoshifumi
    In our area, we are developing new mathematical methods for systems analysis on the basis of theories in optimization and decision making; mathematical programming, game theory, soft computing (fuzzy theory, clustering, support vector machine, chaos theory, swarm intelligence, and rough set theory), and knowledge information processing. Moreover, we apply them to some practical problems.

    Intense Laser Science and Engineering Area

    Associate Professor HABARA Hideaki
    The interactions between high energy laser and plasmas create various plasma instabilities. Revealin the physics of the interactions can lead a critical impact on fast ignition scheme of laser fusion. Basic understaindig of plasma wall interactions in a laser fusion reactor is also studied. We use laser facilities at major institutes and universities in the world.

    Advanced Plasma Engineering Area

    Professor UEDA Yoshio   Assistant Professor IBANO Kenzo
    Materials are the key to unlocking nuclear fusion power as a safe and sustainable energy source. We study the incredibly complex interaction between fusion plasma and materials from both a fundamental and engineering point of view. From such framework, we pursue development of novel plasma generation technology and ion beam technology. Pulsed heat and particle loading effects on refractory materials are also our world leading research subjects.

    High Energy Density Sciences Area

    Professor KODAMA Ryosuke   Associate Professor OZAKI Norimasa   Associate Professor HOSOKAI Tomonao   Assistant Professor NAKAMURA Hirotaka
    We are exploring High Energy Density (HED) science with high-power lasers and x-ray free electron lasers(XFEL). Novel mater, material and devices are being developed utilizing the high energy density states, which has never existed at ambient condition on the earth:
    ・Development of a plasma photonic device and its applications
    Development of a laser accelerator with plasma fibers and its application such as a super transmission electron microscope and a table top XFEL, Intense THz radiation source with a plasma device and exploring of nonlinear optics in vacuum with a plasma mirror.
    ・Creation of matter and material in extreme states or high energy density solid states
    Control of extreme pressures conditions, resulting in creation of super-diamond, which could be harder than normal diamond, solid metallic hydrogen, which would contain a large density of hydrogen and other novel matter, which would be existed in the super earth. 
    These research subjects could not make progress only in the filed of photon science and plasma science but also in the large fields of sciences such as vacuum quantum physics, geophysics, material science, high pressure physics and chemistry, beam and other sciences.Experimental approaches on these studied are conducted using high power laser facilities including XFEL in the world under the domestic and International corporations.

    Advanced Beam Systems Engineering Area

    Associate Professor KATO Yushi
    Electron cyclotron resonance (ECR) ion sources have been widely used for production of high intensity multicharged ion beams for accelerator, heavy particle cancer radiotherapy, space propulsion, bio-nano material fields, as well as implantation in industrial applications. With promoting basic and applied researches of ECR plasma, we are conducting research and development with respect to new beam source responsible for the next generation.
