The utility model provides an electron beam sub-harmonic buncher, comprising a columnar re-entrant type resonant cavity with a central axis, a beam current pipeline extended along the central axis and through which an electron current flows through, a tuner for adjusting the frequency of the re-entrant type resonant cavity and a coupler for feeding the radio frequency power into the re-entrant type resonant cavity; wherein the beam current pipeline comprises a first beam current pipeline and a second beam current pipeline, which respectively stretch into the interior of the beam current pipeline oppositely from the outsides of two circular bottom faces of the re-entrant type resonant cavity; the first beam current pipeline and the second beam current pipeline are respectively provided with a first nose cone end and a second nose cone end, which are located in the re-entrant type resonant cavity; the first nose cone end and the second nose cone end define a clearance; the tuner stretches into the re-entrant ty
