The lab uses supercomputer simulations to uncover the hidden physics of plasma.
AboutAbout the lab
Exploring plasma physics with supercomputers
The Usami Lab studies plasma physics through computer simulation.
Its current theme is to clarify the mechanism of "magnetic reconnection," a phenomenon seen widely from astrophysical objects such as solar flares to laboratory devices such as nuclear fusion devices.
Working together with experiments and observations, the lab reproduces these phenomena on supercomputers.
The lab is a collaborative chair of the Department of Advanced Energy, run by researchers from the National Institute for Fusion Science.
Key terms
- Plasma
- A state in which a gas becomes extremely hot and its atoms split into electrons and ions that move around freely.
- Magnetic reconnection
- A phenomenon in plasma in which magnetic field lines break and reconnect in a different configuration. Magnetic energy is suddenly converted into heat and particle motion.
- Particle simulation
- A method that tracks on a computer the motion of each individual particle making up a plasma, in order to study the behavior of the plasma as a whole.
ResearchResearch themes
The lab investigates the physics of plasma through computer simulation. Using supercomputers, it reproduces and studies the mechanism of magnetic reconnection and the various processes that accompany it.
