“…For the sake of calculation simplicity, the input (upstream) Bragg reflector was replaced by a lumped mirror with the reflection coefficient R in ¼ 1. The efficiency of LF generation in these regimes was about 3%-5%, which is much lower compared with the results of the previous experiments [1][2][3][4] and can be explained by the fact that the optimal beam parameters for the high-harmonic radiation are substantially different from those of the conventional single-frequency FEM regime. It should also be noted that for the chosen cavity geometry the radiation at harmonics higher than s > 3 and n > 2 was rather small.…”

“…Evidently, for the efficient LF and HF coexcitation by the same electron beam all the conditions (2), (4), and (6) should be fulfilled simultaneously. Figure 2 presents a dispersion diagram illustrating interaction of the beam electrons with LF and HF waves in the FEM multiplier.…”

“…The radiation parameters achieved in these experiments (output power, electron efficiency, stability of the narrow-band operation regime, etc.) allow JINR-IAP FEM to be used in several physical and engineering applications, in particular, to study the heating stress effect in high-gradient accelerating structures for the CLIC project (CERN) [3,4].…”

The frequency multiplication effects in high-power free-electron masers (FEM) with Bragg cavities were studied to provide the advance of the oscillators into short-wavelength bands. Theoretical analysis of frequency-multiplying FEMs was carried out within the framework of the averaged coupled-wave approach. Proof-of-principle experiments were performed based on a moderately relativistic induction linac LIU-3000 (JINR). As a result, an FEM multiplier operated with a megawatt power level in the 6-mm and 4-mm wavelength bands at the second and third harmonics, respectively, was realized. The possibility of using two-mode bichromatic FEMs for powering a double-frequency accelerating structure was discussed.
