研究目的
Investigating the three-dimensional dynamics of a laser-driven plasma plume expanding in a transverse magnetic field and the growth of the magnetized Rayleigh-Taylor instability.
研究成果
The study demonstrates the complex three-dimensional dynamics of a laser-driven plasma plume in a transverse magnetic field, highlighting the development of the fluidlike magnetized Rayleigh-Taylor instability. The platform opens the door to further studies of this instability in different regimes and geometries.
研究不足
The study is limited by the strength of the magnetic field and the laser parameters used. The understanding of the plasma dynamics and instabilities is still evolving.
1：Experimental Design and Method Selection:
The experiments are performed on three different facilities with similar laser parameters, irradiating a Teflon foil target in a vacuum with an externally applied, pulsed magnetic field.
2：Sample Selection and Data Sources:
The plasma plume expansion is observed under a 20 T transverse magnetic field.
3：List of Experimental Equipment and Materials:
Pulsed-power driven Helmholtz coil for magnetic field generation, nanosecond-duration laser pulse.
4：Experimental Procedures and Operational Workflow:
The laser irradiates the target, and the plasma expansion is observed interferometrically.
5：Data Analysis Methods:
The data are complemented by three-dimensional, single-fluid, bi-temperature resistive magneto-hydrodynamic simulations.
