Ion acoustic waves in plasmas with collisional electrons
- 1. Department of Physics, University of Alberta, Edmonton, Alberta, T6G 2J1 (Canada)
Description
We have developed an analytical theory of ion acoustic wave (IAW) damping and electron heat conductivity in plasmas with an arbitrary electron collisionality. We have found that deviations from the collisionless electron Landau damping occur for the wave numbers kλei∼Z2/3, where λei is the electron mean free path for collisions with ions. In the regime of intermediate collisionality the IAW damping is proportional to k4/7 and the nonlocal electron heat conductivity is proportional to k-4/7. The transition into the hydrodynamic regime occurs for kλei∼0.1Z1/2
