Hi. I'm MinSup Hur. Welcome to my CPL homepage.
We study plasmas by computer simulations and theory. Among so many subjects in plasma science, we pursue understanding the laser-plasma interaction and related applications.
In particular, we have studied
- Shock in a plasma, and the shock ion acceleration
- Electron trapping in a plasma bubble for Laser Wakefield Electron Acceleration (LWFA)
- Raman backward amplification of radiation
- Strong THz emission from laser and underdense plasmas.
- Magnetic Confined Plasma Device with SOLPS-ITER code package.
DESCRIPTION ON 'PLASMA' FOR NON-SPECIALISTS
Plasma can be considered simply as a 'gas' of ionized particles. That is, the plasma is a collection of many electrons and ions which are not bound to each other. The big difference from usual gas (or fluid) is that the plasma is strongly susceptible to electromagnetic fields as it is composed of charged particles. The response of the plasma particles is not random, but is collective, and also nonlinear. Those collective and nonlinear behavior is the basis of many interesting applications and natural phenomena.
