摘要

在本研究中，我们研究了线性液态金属流在用作高重复脉冲功率放电的负载和激光靶的薄片时对磁场的响应。当磁场垂直于液态金属流时，液态金属流在保持厚度的同时发生变形。这种方法可以在 Z-pinch 放电和替代 X-pinch 放电中降低电流并增强光源。然而，当磁场平行于片状液态金属流时，低频波动更为明显。这些发现表明，将液态金属流与磁场相结合可有效促进高重复脉冲功率放电和激光操作。

Development of liquid metal targets for high-repetition intense laser and pulsed-power discharge applications

In this study, we investigate the response of linear liquid metal flow to a magnetic field when used as a load for high-repetition pulsed-power discharges and as a sheet for a laser target. When a magnetic field was applied perpendicular to the liquid metal flow, the flow deformed while maintaining its thickness. This approach may reduce current and enhance light sources in Z-pinch and alternative X-pinch discharges. However, low-frequency fluctuations were more prominent when the magnetic field was applied parallel to the liquid metal flow in sheet form. These findings suggest that combining liquid metal flow with a magnetic field could effectively facilitate high-repetition pulsed-power discharges and laser operations.

期刊介绍： High Energy Density Physics is an international journal covering original experimental and related theoretical work studying the physics of matter and radiation under extreme conditions. ''High energy density'' is understood to be an energy density exceeding about 1011 J/m3. The editors and the publisher are committed to provide this fast-growing community with a dedicated high quality channel to distribute their original findings. Papers suitable for publication in this journal cover topics in both the warm and hot dense matter regimes, such as laboratory studies relevant to non-LTE kinetics at extreme conditions, planetary interiors, astrophysical phenomena, inertial fusion and includes studies of, for example, material properties and both stable and unstable hydrodynamics. Developments in associated theoretical areas, for example the modelling of strongly coupled, partially degenerate and relativistic plasmas, are also covered.
