We present a version of the frequency-tunable gyrotron operating in a wide frequency range (0.1–0.26 THz) with an output radiation power of up to 260 kW. Multilevel analysis and combined optimization of its electron-optical and electrodynamical systems are performed. The gyrotron is designed for operation with the JASTEC-10T100 cryomagnet or its analogs. Efficiency of single-stage recovery in this system is analyzed. A collector system is proposed, which is capable of collecting electron beams effectively during gyrotron operation in the entire specified frequency range.
