Description
The kinetic instability of the obliquely propagating drift magnetosonic
wave for temperature anisotropic low beta plasmas is studied by using
the gyro-kinetic model. The interplay between the temperature anisotropy
and the density inhomogeneity free energy sources is discussed in order
to provide stabilization of drift instability by the temperature
anisotropy effect. It is shown that the anisotropy suppresses the growth
rate when the anisotropy ratio A e , i ( = T ⊥ ( e
, i ) / T ∥ ( e , i ) ) is greater than unity,
whereas it enhances the growth rate for A e , i < 1 .
Comparison of kinetic instability with reactive instability [Naim et
al., Phys. Plasmas 21, 102112 (2014)] and the scaling of growth time
with the diffusion and the anisotropy relaxation times are presented.
Additionally, the stability analysis applicable to a wide range of
plasma parameters is also performed.
