Zones of Frequency Locking by an External Signal in a Multimode Gyrotron of a Megawatt Power Level

详细

We study locking of the oscillation frequency of the operating TE_28,12 mode by an external monochromatic signal in a multimode gyrotron operated at a frequency of 170 GHz in the switch-on regime close to the real one. Locking zones, i.e., regions of single-mode generation at the external-signal frequency are found on the “current—detuning” plane of parameters. It is shown that as the number of competing modes increases, the maximum achievable current decreases, and the locking zones contract at sufficiently high currents.
