Kunioki Mima
is a Japanese plasma physicist. He is known for his contributions to the theory of turbulent transport in plasmas, and in particular the derivation of the Hasegawa–Mima equation in 1977, which won him the 2011 Hannes Alfvén Prize. Early life and career Mima studied physics at Kyoto University and graduated with a bachelor's degree in 1968 and a PhD in 1973. He was a post-doctoral student at Hiroshima University until 1975 and then started work at Osaka University, where he became an assistant professor in 1978 and a professor in 1984. From 1995 to 1999, he was director of the Institute of Laser Engineering. There, his work involved laser fusion (experiments with the Gekko XII laser and FIREX program), free electron lasers, relativistic plasmas and laser-plasma interaction. Honors and awards Mima is a Fellow of the American Physical Society and a Member of the Physical Society of Japan and the Japan Society of Plasma Science at Nuclear Fusion Research. He was a c ...

Relativistic Plasma
Relativistic plasmas in physics are plasmas for which relativistic corrections to a particle's mass and velocity are important. Such corrections typically become important when a significant number of electrons reach speeds greater than 0.86 c (Lorentz factor \gamma=2). Such plasmas may be created either by heating a gas to very high temperatures or by the impact of a high-energy particle beam. A relativistic plasma with a thermal distribution function has temperatures greater than around 260 keV, or 3.0 GK (5.5 billion degrees Fahrenheit), where approximately 10% of the electrons have \gamma > 2. Since these temperatures are so high, most relativistic plasmas are small and brief, and are often the result of a relativistic beam impacting some target. (More mundanely, "relativistic plasma" might denote a normal, cold plasma moving at a significant fraction of the speed of light relative to the observer.) Relativistic plasmas may result when two particle beams collide at speeds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turbulence
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers. Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This increases the energy needed to pump fluid through a pipe. The onset of turbulence can be predicted by the dimensionless Rey ...

Zonal Flow (plasma)
In toroidally confined fusion plasma experiments the term zonal flow means a plasma flow within a magnetic surface primarily in the poloidal direction. This usage is inspired by the analogy between the quasi-two-dimensional nature of large-scale atmospheric and oceanic flows, where zonal means latitudinal, and the similarly quasi-two-dimensional nature of low-frequency flows in a strongly magnetized plasma. Zonal flows in the toroidal plasma context are further characterized by * being localized in their radial extent transverse to the magnetic surfaces (in contrast to global plasma rotation), * having little or no variation in either the poloidal or toroidal direction—they are ''m'' = ''n'' = 0 modes (where ''m'' and ''n'' are the poloidal and toroidal mode numbers, respectively), * having zero real frequency when analyzed by linearization around an unperturbed toroidal equilibrium state (in contrast to the geodesic acoustic mode branch, which has finite frequency). * Arising ...

Akira Hasegawa
is a theoretical physicist and engineer who has worked in the US and Japan. He is known for his work in the derivation of the Hasegawa–Mima equation, which describes fundamental plasma turbulence and the consequent generation of zonal flow that controls plasma diffusion. Hasegawa also made the discovery of optical solitons in glass fibers, a concept that is essential for high speed optical communications. Hasegawa was the first to suggest the existence of optical solitons in 1973. In 1974, he (together with Liu Chen) showed that plasmas could be heated with the kinetic Alfvén wave. Hasegawa and Chen introduced the concept of the kinetic Alfven wave to illustrate the microscopic process of the Alfven wave heating. In 1977, Hasegawa introduced the Hasegawa–Mima equation to describe turbulence in Tokamak plasmas and then further developed it in the 1980s (with Masahiro Wakatani) to obtain the Hasegawa-Wakatani equation. The equation predicted an ''inverse cascade'' in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physical Society Of Japan
The Physical Society of Japan (JPS; 日本物理学会 in Japanese) is the organisation of physicists in Japan. There are about 16,000 members, including university professors, researchers as well as educators, and engineers. The origins of the JPS go back to the establishment of the Tokyo Mathematical Society in 1877, as the first society in natural science in Japan. After being renamed twice, as Tokyo Mathematical and Physical Society in 1884 and as Physico-Mathematical Society of Japan in 1919, it eventually separated into two in 1946, and the Physical Society of Japan was formed. Takeo Shimizu (清水武雄), a contributor to the improvements to the Wilson cloud chamber and the last President of the Physico-Mathematical Society, was also the first president of JPS. Purpose The primary purposes of the JPS are to publish research reports of its members and to provide its members with facilities relating to physics.
