Instability in a magnetised collisional plasma driven by a heat flow or a current

A R Bell, R J Kingham, H C Watkins, J H Matthews2020年Plasma Physics and Controlled FusionIF 2.2出版社

We solve the linearised Vlasov-Fokker-Planck (VFP) equation to show that heat flow or an electrical current in a magnetized collisional plasma is unstable to the growth of a circularly polarised transverse perturbation to a zeroth order uniform magnetic field. The Braginskii [1965 Rev Plasma Phys1 205] transport equations exhibit the same instability in the appropriate limit. This is relevant to laser-produced plasmas, inertial fusion energy (IFE) and to dense cold interstellar plasmas.

我々は線形化されたVlasov-Fokker-Planck(VFP)方程式を解き、磁化された衝突性プラズマにおける熱流または電流が、ゼロ次の一様磁場に対する円偏光横摂動の成長に対して不安定であることを示す。Braginskii[1965 Rev Plasma Phys1 205]の輸送方程式は、適切な極限において同じ不安定性を示す。これは、レーザー生成プラズマ、慣性核融合エネルギー(IFE)、および高密度低温星間プラズマに関連する。
