Abstract: | Due to high selectivity of open cavity, wider electron beams with higher current can be used in orotron as compared with other Cherenkov devices. It provides important advantages at short millimeter and submillimeter waves. Theory and preliminary experiments in the short part of millimeter and long part of submillimeter wavelength range show that orotron with operating voltage of few kV can generate significantly higher output power than existing BWOs. Combined electronic and mechanical frequency tuning in the band of about of octave has been obtained. |
