韧致辐射对等离子体中快电子的影响

Effect of bremsstrahlung radiation emission on fast electrons in plasmas

Ola Embréus, Adam Stahl, Tünde Fülöp

摘要:

韧致辐射是等离子体中高能电子能量损失的重要机制。在本文中,我们研究了自发韧致辐射对电子分布的动量-空间结构的影响,充分考虑了有限能量光子的发射。我们发现,电子加速的电场可以达到显着更高的能量比预期的能量损失的考虑。此外,我们表明,软光子的发射可以显着贡献的各向异性分布的电子的动力学。

英文摘要:

Bremsstrahlung radiation emission is an important energy loss mechanism for energetic electrons in plasmas. In this paper we investigate the effect of spontaneous bremsstrahlung emission on the momentum-space structure of the electron distribution, fully accounting for the emission of finite-energy photons. We find that electrons accelerated by electric fields can reach significantly higher energies than what is expected from energy-loss considerations. Furthermore, we show that the emission of soft photons can contribute significantly to the dynamics of electrons with an anisotropic distribution.
