“…For the analysis of peer-to-peer locking, consider a system of two coupled gyrotrons, which are assumed identical, except for small detuning of the eigenfrequencies, i.e., ω 1,2 = ω 0 ± ∆ω/2, where ∆ω << ω 0 and the subscripts 1 and 2 refer to the first and the second gyrotron, respectively. In that case, instead of (4) we obtain a system of two coupled DDEs [27,28]:…”

“…Following [25][26][27][28], consider the situation when the normalized delay time is small, i.e., τ d << 1. In that case, we can neglect the delay in the right-hand sides of (10), i.e., A 1,2 (τ − τ d ) ≈ A 1,2 (τ), and obtain the system of ordinary differential equations (ODEs):…”

“…Therefore, it is beneficial to slightly reduce the current. With the increase in coupling, the amplitudes will increase and approach the optimal value at which the maximal efficiency is provided [28]. So, we set the current parameter to I 0 = 0.05.…”

“…In [27,28], we proposed a simple model, which extends the analysis presented in [25,26] to the peer-to-peer locking of gyrotrons. This model allows for a comprehensive theoretical analysis of peer-to-peer locking regimes, including the use of modern software tools for the bifurcation analysis of nonlinear dynamical systems.…”

Peer-to-peer locking is a promising way to combine the power of high-power microwave oscillators. The peer-to-peer locking of gyrotrons is especially important because arrays of coupled gyrotrons are of special interest for fusion and certain other applications. However, in case of coupled microwave oscillators, the effect of delay in coupling is very significant and should be taken into account. In this article, we present the model of two delay-coupled gyrotrons. We develop an approximate theory of phase locking based on the generalized Adler’s equation, which allows for the treatment of in-phase and anti-phase locking modes. We also present a more rigorous bifurcation analysis of phase locking by using XPPAUT software under the limitation of small delay time. The structure of the phase-locking domains on the frequency-mismatch–coupling-strength plane of parameters is examined. Finally, we verify the results by numerical simulations in the case of finite delay time. The simulations reveal various regimes, including peer-to-peer locking, the suppression of one gyrotron by another, as well as the excitation of one gyrotron by another.
