What reading level is The Gain And the Noise Figure of the Helical Traveling Wave Tube book?
To quickly assess the difficulty of the text, read a short excerpt:
By sacrificing some few percent of accuracy, we can bring the domain of vadidity down to « = 2 with not too great trepidation. This brings the allowed values of b/a down to, 53» However, the entire range still lies in the range b/a < . U62, so v/e ceui expect the last curve in Figure 6 to be valid and the noise figure decreases with beam voltage. For this choice of parameters, c.^ = . O525 I '^/(b/a). When b/a = . 8, c " . 161, and for all reasonable currents c.^ is much less than c-_. , so the amplifying region is broad. When b/a ■ . 6, c-q •= °iOk ^°^ ^ current I = Ul ma, which is still too large for practice. Consequently, we need not worry nnich about the restriction c, q < c, qj^, since it is generally satisfied In practice. 6^ Dependence of Gain and Hoise Figure on Beam Radius for Constant Current . We shall now keep a, u, I, and V fixed, and allow b to vary. Since a is fixed, we may take b/a as the independent variable. The work of this section corresponds to varying the beam radius while fixing the total current, so we effectively vary the current density.
