Abstract

947,552. Travelling wave tubes. SIEMENS & HALSKE A.G. April 27, 1962 [April 27, 1961], No. 16242/62. Drawings to Specification. Heading H1D. In a travelling wave tube the electron beam has applied thereto a longitudinal magnetic field and interacts with the wave travelling along a delay line, the delay line carrying a negatively circularly polarized wave having transverse electrical field components, the phase velocity of the wave being equal to the beam velocity. The delay line is preferably a four start helix, Fig. 5 (not shown). The signal on one pair of opposite helices is delayed #/2 relatively to that on the other pair of helices. The beam is braked between the delay line and the collector.
