| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Plasma is the fourth state of matter, in which individual electrons and ions move around at various speeds. The velocity distribution function is a statistical description that connects particle kinetics and macroscopic parameters in many-body systems. The Maxwellian distribution is the most fundamental velocity distribution function, which holds in thermodynamic equilibrium states. However, it does not necessarily hold for magnetized plasmas, often in non-equilibrium states. The velocity distribution function takes various forms depending on the essential physics in the system of interest. Here, we propose a novel approach to select the valid form of the velocity distribution function based on Bayesian statistics. We formulate the Bayesian inference of ion velocity distribution function and apply it to laser-induced fluorescence spectra in a magnetized plasma. | |
