- Abstract
- 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(2). The numerical results are presented for the external electron-energy gain and its trajectory in a nonrelativistic gamma(e)=1 and stationary v(0)=0 warm magnetized plasma-filled waveguide. Results shows that for an electron-cyclotron frequency omega(c) greater than the electron-plasma frequency omega(p), a 100 keV electron acquires a 1.74 MeV energy in a 2.5 cm distance for plasma density n(0)=1.08x10(17)/m(3), magnetic field B(0)=0.193 T, microwave frequency f=7.64 GHz, plasma-electron thermal velocity v(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. (C) 2008 American Institute of Physics. [DOI: 10.1063/1.2988899]
