论文摘要
使用佩斯利模式的目标产生100 kt级的磁场。激光照射会在目标上诱导局部电荷分离，从而产生沿凹面表面的表面电流，从而产生磁场。对于$ 10^{21} $ w/cm $^2 $的激光强度，目标会产生150 kt磁场。我们开发了一个简单的模型，将磁场描述为激光强度和目标半径的函数。双佩斯利配置将磁场的寿命扩展到皮秒刻度。即使简化了佩斯利设计，也会产生可比的结果。因此，它是一个适用于磁场应用，例如100 kt磁场的产生和磁重新连接的强大和模块化靶标。
A target using a paisley pattern generates 100-kT-level magnetic fields. Laser irradiation induces local charge separation on the target, which creates surface currents along the concave surface, generating a magnetic field. For a laser intensity of $10^{21}$ W/cm$^2$, the target generates a 150-kT magnetic field. We developed a simple model to describe the magnetic field as a function of laser intensity and target radius. A double paisley configuration extends the lifetime of the magnetic field to the picosecond scale. The paisley design generates comparable results even if it is simplified. Thus, it is a robust and modular target suitable for magnetic field applications such as 100-kT magnetic field generation and magnetic reconnection.
