600-T Magnetic Fields due to Cold Electron Flow in a simple Cu-Coil irradiated by High Power Laser pulses
摘要:
提出了一种新的简单的冷电子流产生强磁场的机制。当激光强度为5.7 × 10^15 Wcm^-2时,在自由空间中会产生600 T的强磁场。理论分析表明,磁场强度与激光强度成正比。这种强磁场为研究激光-等离子体物理,特别是快点火激光聚变研究和实验室天体物理提供了一个新的实验平台。
英文摘要:
A new simple mechanism due to cold electron flow to produce strong magnetic field is proposed. A 600-T strong magnetic field is generated in the free space at the laser intensity of 5.7x10^15 Wcm^-2. Theoretical analysis indicates that the magnetic field strength is proportional to laser intensity. Such a strong magnetic field offers a new experimental test bed to study laser-plasma physics, in particular, fast-ignition laser fusion research and laboratory astrophysics.
