The full dispersion equation for linear Alfvén ion cyclotron waves propagating along a uniform magnetic field in a finite beta turbulent plasma with anisotropic ions is solved numerically for complex wavenumbers. The influence of a stationary, small scale Langmuir background turbulence on the real part of the wavenumber and the spatial growth rate of the Alfvén ion cyclotron instability is investigated. It is found that the presence of turbulence makes the spatial growth substantial before the wave comes out of a finite length laboratory plasma. The applicability of the results to a tandem mirror machine is discussed.
有限β湍流等离子体中，各向异性离子沿均匀磁场传播的线性阿尔芬离子回旋波的完整色散方程，针对复波数进行了数值求解。研究了稳态小尺度朗缪尔背景湍流对波数实部及阿尔芬离子回旋不稳定性空间增长率的影响。结果表明，湍流的存在使得波在从有限长度实验室等离子体出射前即获得显著的空间增长。最后讨论了这些结果在串列镜装置中的适用性。
