Kinetic Alfvén waves in a deuterium-tritium fusion plasma with slowing-down distributed α-particles
文献摘要：
The dispersion relation and damping rate of kinetic Alfvén waves(KAWs)in a deuterium-tritium fusion plasma with slowing-down distributed α-particles are investigated using the kinetic theory.The variations of wave frequency and damping rate with respect to the α concentration(nα/ne)and perpendicular wave number(k⊥)are studied from a numerical way.The results show that the fluctuation of α concentration slightly affects the frequency and damping rate of KAWs at low nα/ne.In addition,the frequency and the damping rate increase as the k⊥ and the background temperature Te increase.For comparison,the calculations are performed also in the case of α-particles following an equivalent Maxwellian distribution.For a given k⊥,the value of the frequency obtained in the slowing-down distribution case is smaller than that obtained in the Maxwellian distribution case.Conversely,the value of the damping rate obtained in the slowing-down distribution case is slightly larger than that obtained in the Maxwellian distribution case.
