Welcome to our group website!
My group focuses on experimental and numerical researches on High Energy Density (HED) Plasmas, extreme states of matter that exists in interior of stars and fusion plasmas. Inertial Confinement Fusion (ICF), known as Laser Fusion, is one of the two main approaches to harness clean, unlimited, reliable energies from fusion reactions in laboratories. Despite the huge potential, achieving ignition for sustainable fusion reactions is still a grand challenge even at the world largest laser facility, National Ignition Facility at Lawrence Livermore National Laboratory. Studying behaviors of non-stationary and non-equilibrium HED plasmas helps us understand details of fusion plasmas and the evolution of stars.
Our research topics include characterization of HED plasmas using an ultra-intense, short-pulse laser. Because of the very short time scale of the laser pulse less than a few picoseconds, matters can be heated to a few million degrees. This rapid heating with an intense short-pulse laser could serve as an ignitor of fusion fuel in an advanced high-gain ICF scheme, Fast Ignition.
Our ongoing research topics are
- Laser Fusion (Inertial Confinement Fusion (ICF), advanced Fast Ignition (FI))
- Intense short pulse laser matter interaction
- Development of high energy x-ray diagnostics
- Generation of bright x-ray source and charged particle beams
