Abstract
The temporal dynamics of excitation of a free-electron maser with a pr olonged and low-e microwave system is studied taking into account the feedback frequency dispersion, the HF space charge, and the undulator tapering. It is shown that in spite of a great many longitudinal modes excited at the small-signal stage, even a rather broadband feedback d ispersion significantly shortens the transient time and provides a sta ble single-frequency operating regime.
