FIELD: electronic engineering; slow-wave structures of traveling-wave tubes of primarily packaged design integrated with periodic magnetic focusing structure. ^ SUBSTANCE: proposed pin-type periodic slow-wave structure is packaged. Each pin carries transit-time tube in the form of cylinder that has through slit throughout its entire length. This slit is aligned with cylinder generating line of transit-time tube. Angle alpha of slit turn relative to pin axis in plane perpendicular to slow-wave structure axis ranges within arc sin(l/d) <= alpha < 180 deg., where l is pin width in plane perpendicular to slow-wave structure axis, m; d is outer diameter of transit-time tube, m. Slow-wave structure design ensures reduced diameter of resonator in operating frequency range thereby reducing its transverse dimensions. ^ EFFECT: provision for miniaturization of traveling-wave tube and devices built around it. ^ 11 cl, 10 dwg |
