摘要：

The bounce model has been used to calculate the growth rate of the m = 1 mode of a linear âpinch having an isotropic Maxwellian ion distribution function rotating with angular velocity ω. For short wavelength, the perturbation rotates with the ions; for longer wavelength it rotates more slowly. The plasma is unstable above a critical wavelength, with growth times τ ≈25 μsec for typical values of ω. This result falls between the magnetohydrodynamic result of τ = ∞ (stable) and the rigid body limit of τ ≈ ω-1. Consideration of the m = 2 mode is also included.
