Research activities:
There are several groups and machines for the investigations of experimental plasma physics, computer simulation and theory at Utsunomiya University.

Professors Y. Nishida, N. Yugami and Dr. H. Ito are studying nonlinear wave-particle interactions in a plasma irradiated by high power microwave with frequencies of 2.86 and 9 GHz. They are the pioneer of the investigation on the plasma based particle acceleration phenomena, and presently they are studying the plasma based acceleration physics by employing high power microwave or short pulse high power laser. They are also studying coherent radiation sources in microwave through tera-hertz range by employing the system called ''RIFLE'' (Radiation from Interaction of Ionization Front with Lined Electrostatic field) or called ''DARC'' (DC to AC Radiation Converter), which is the radiation occurred from the interaction of moving ionization front with the lined electrostatic field. Large amplitude solitions and chaos in the plasma in both ion and electron wave regime are also intensively studied. New plasma sources for ion beam sources and/or plasma processing are under investigation.

Prof. T. Nagasawa and Dr. Y. Saitou carry out experimental research on nonlinear phenomena in plasmas such as shock waves, solitons and chaos. It is also their subject matter to study beam-plasma and wave-particle interaction, as well as plasma production. They also engage in interaction between plasma and supersonic waves using a double plasma device, and study new plasma sources for plasma processing, which has temperature gradient in space.

Prof. S. Kawata and Dr. T. Nakamura, have worked on mainly Ion Beam Inertial Confinement Fusion by computer simulations including a fuel pellet implosion, beam transport and beam-target interaction, in addition to intense particle beam transport, high-energy particle acceleration, development of new computer simulation methods, the Vlasov simulation for laser-matter interaction, and a computer-assisted simulation environment relating to the above researches.

Professors N. Asano, H. Nakajima and T. Yajima are studying nonlinear wave theory, field theory and chaotic processes in continuous or discrete systems.
