Accurate measurement of magnetic fields produced by laser-driven coil targets via proton radiography Open
The spatiotemporal evolution of electromagnetic fields generated by a relativistic-intensity laser pulse irradiating a capacitor–coil target was diagnosed using proton radiography. In the experiments, both an electromagnetic pulse (EMP) pr…

Species stratification and suprathermal ion velocity separation driven by an electrostatic collisionless shock inside an ICF hohlraum Open
In indirect-drive inertial confinement fusion, there are significant non-equilibrium kinetic effects that deviate from hydrodynamic descriptions in the region of relatively high temperature and low density. Crucially, the complex interfaci…

Structure of weakly collisional shock waves of multicomponent plasmas inside hohlraums of indirect inertial confinement fusions Open
In laser-driven indirect inertial confinement fusion (ICF), a hohlraum--a cavity constructed from high-Z materials--serves the purpose of converting laser energy into thermal x-ray energy. This process involves the interaction of low-densi…

First Proof of Principle Experiment for Muon Production with Ultrashort High Intensity Laser Open
Muons, which play a crucial role in both fundamental and applied physics, have traditionally been generated through proton accelerators or from cosmic rays. With the advent of ultra-short high-intensity lasers capable of accelerating elect…
