Abstract: An effective narrow-band free-electron maser (FEM) with reversed axial guide magnetic field, based on a corrugated high-selectivity Bragg resonator with a jump in the ripple phase, has been constructed and tested. The FEM operates at 30 GHz with characteristics of the output radiation (power, pulse duration, spectrum width) and stability of the generation regime that allow the device to be used in testing electrodynamic components for future electron-positron supercolliders. Experiments have been performed with a high-Q resonator operating on a resonant load, which can be used to model the degradation of an accelerating structure of the CLIC collider (CERN) as a result of thermal fatigue caused by the multiply repeated ($\sim$10$^5$ cycles) action of microwave pulses.
