On ion-dust streaming instability in a collisional magnetized plasma with warm dust

摘要

This brief communication discusses theoretically a resistive ion-dust streaming instability in a collisional dusty plasma, where the ions and electrons are magnetized, and the dust is unmagnetized. The instability is driven by ions streaming along the magnetic field. The emphasis is on the case where the dust has large thermal speed, and where the ion drift speed ≤ is the ion thermal speed. Application to possible laboratory experimental parameters is considered.
