A coupled-mode analysis of signal and noise propagation on accelerated beams is discussed for two particular potential variations. The first case, which has been investigated by Haddad and Adair, assumes a d-c potential achievable only by the use of grids. A predicted noise reduction scheme using insertion of additional power into the fast space-charge-wave is shown to be rather limited. The second case discussed is the space-charge-limited diode region, and it is demonstrated that it does not show any noise reduction at all under the assumptions of the coupled-mode theory. Author
