EFFECTS OF LINE-TYING ON HOT ELECTRON INTERCHANGE MODE
LINE-TYING效应对热电子交换模的影响

The effects of cold plasma and conducting end plates on interchange instability of finite-length hot electron plasma are studied. A dispersion relation including line-tying is derived, and new stability criteria are found. Strong line-tying effect can greatly reduce the threshold of densky ratio needed for stabilizing interchange mode of hot electrons. The modes with low m and long wavelength may be stabilized more easily.
