The effect of plasma-electron collision and their thermal motion is investigated on the externally injected electron in a warm magnetized plasma-filled cylindrical waveguide of cross section of 13.68 cm{sup 2}. The numerical results are presented for the external electron-energy gain and its trajectory in a nonrelativistic {gamma}{sub e}=1 and stationary v{sub 0}=0 warm magnetized plasma-filled waveguide. Results shows that for an electron-cyclotron frequency {omega}{sub c} greater than the electron-plasma frequency {omega}{sub p}, a 100 keV electron acquires a 1.74 MeV energy in a 2.5 cm distance for plasma density n{sub 0}=1.08x10{sup 17}/m{sup 3}, magnetic field B{sub 0}=0.193 T, microwave frequency f=7.64 GHz, plasma-electron thermal velocity v{sub th}=0.2c, and plasma-electron collision frequency {nu}=4 GHz, which is lower than the 7 MeV electron energy in a cold magnetized plasma-waveguide case. Space-charge effects and other nonlinear effects are assumed to be negligible in this model.
