Abstract :
Analytical expressions for the noise figure of a traveling-wave amplifier (TWA) preceded by a nonuniform drift space are derived. Numerical results show that the noise figure for an accelerated beam has a minimum at a specific drift length. Also, when the noise figure is plotted as a function of heater power, it shows a minimum value.
