Description:
Author(s): M. D. Campanell, A. V. Khrabrov, and I. D. Kaganovich A condition for sheath instability due to secondary electron emission (SEE) is derived for low collisionality plasmas. When the SEE coefficient of the electrons bordering the depleted loss cone in energy space exceeds unity, the sheath potential is unstable to a negative perturbation. This result ex... [Phys. Rev.
