标题： Scaling of thin wire cylindrical compression after 100 fs Joule surface heating with material, diameter and laser energy

摘要： 我们首次对微米尺寸导线在飞秒激光脉冲照射下由返回电流驱动的内爆尺度进行了系统实验验证。 利用基于X射线自由电子激光的成像技术，具有亚微米空间分辨率和飞秒时间分辨率，并结合流体动力学和粒子模拟，我们揭示了返回电流密度如何精确地依赖于导线直径、材料特性和入射激光能量。 我们发现由于几何影响的电子逃逸动力学导致与简单理论预测的偏差。 这些结果完善并确认了高能密度物理和惯性约束聚变研究中预测建模的关键尺度定律。 显示英文摘要

摘要： We present the first systematic experimental validation of return-current-driven implosion scaling in micrometer-sized wires irradiated by femtosecond laser pulses. Employing XFEL-based imaging with sub-micrometer spatial and femtosecond temporal resolution, supported by hydrodynamic and particle-in-cell simulations, we reveal how return current density depends precisely on wire diameter, material properties, and incident laser energy. We identify deviations from simple theoretical predictions due to geometrically influenced electron escape dynamics. These results refine and confirm the scaling laws essential for predictive modeling in high-energy-density physics and inertial fusion research.
