| Popis: | This paper adds new findings to the recently described hampering of electron cooling by electron trapping in a developing electrostatic potential well between the two cold walls [D. I. Kiramov and B. N. Breizman, Phys. Plasmas 27, 022302 (2020)]. We show that the self-consistent process of the potential well formation and electron trapping is tractable analytically when the end walls reflect most of the incoming electrons. For immobile ions, this process creates a steady-state that retains a significant fraction of the initial electron kinetic energy. We also describe the subsequent slow decay of the system due to ion motion. |
