Spurious excitation of a low-frequency near-cutoff wave in the presence of the operating high-frequency traveling wave is considered for a free-electron maser. The temporal dynamics of the competition of the waves is studied. It is shown that the effect of mutual scattering of the waves can result in a significant decrease of the starting current for the spurious wave. (C) 2000 Elsevier Science B.V. All rights reserved.
