“…For example, the scheme of a two-stage FEL, in which the first stage contains a conventional magnetostatic undulator and the generated radiation serves as the pump at the second stage, is discussed in [6]. FEL scattrons pumped from a high-power millimeter-wave gyrotron are considered in [7][8][9]. Since papers [6][7][8][9] discuss the generation of infrared radiation, electron beams with energies of the order of several megaelectronvolts are considered there.…”

However, it follows from the results of these papers that such devices can, in principle, be realized in the terahertz range for accelerating voltages of the order of a few hundred kilovolts.…”

We present the results of numerical simulation of the self-modulation processes in an amplifier based on the effect of stimulated scattering of two counterpropagating transverse electromagnetic waves by a relativistic electron beam (FEL amplifier). Two models of the studied system are considered. One model allows for the effects of overbunching of electrons and is based on the modified method of macroparticles. The other is a simplified wave model obtained in the approximation that the amplitude of a combination wave is small if the nonlinearity of the electron-beam processes is negligibly small. The mechanisms of self-modulation are studied. The scenarios of transition to chaos, observed with increase in the input-signal intensity and system length, are examined.

Gyrotrons as High-Frequency Drivers for Undulators and High-Gradient Accelerators

et al. 2022

View full text Add to dashboard Cite

Gyrotrons are used as high-power sources of coherent radiation operating in pulsed and CW regimes in many scientific and technological fields. In this paper, we discuss two of their numerous applications. The first one is in gyrotron-powered electromagnetic wigglers and undulators. The second one is for driving high-gradient accelerating structures in compact particle accelerators. The comparison, between the requirements imposed by these two concepts on the radiation sources on one hand and the output parameters of the currently available high-performance gyrotrons on the other hand, show that they match each other to a high degree. We consider this as a manifestation of the feasibility and potential of these concepts. It is believed that after the first successful proof-of-principle experiments they will find more wide usage in the advanced FEL and particle accelerators.
