Abstract

1,146,444. Velocity-modulated tubes. SIEMENS A.G. 14 April, 1966 [15 April, 1965], No. 16296/66. Heading HID. In a microwave/D.C. converter, the microwave signal produces a uniform increase in the drift velocity of an electron beam, the subsequent retardation of which by a gridded collector system provides the D.C. output. In one embodiment (Fig. 1, not shown), the microwave signal is applied to a Cuccia coupler to produce a fast cyclotron wave on an electron beam moving in an axial magnetic field, the cyclotron wave being subsequently converted to a synchronous wave-with a consequent uniform increase in the drift velocity of the beamby an abrupt reversal in sense of the magnetic field. Instead of a Cuccia coupler, a waveguide providing a circularly polarized electric field may be employed. In another embodiment, Fig. 3, which dispenses with a magnetic field, the coupler is in the form of a pair of parallel electrodes twisted about the beam to impose upon the latter a continuous radial deflection, such that the resultant beam rotates around a conical surface, the collector 5 with its grid 6 being of appropriately concave shape to ensure normal receipt of the beam. The coupler in this embodiment may be in the form of a twisted rectangular waveguide (Fig. 4, not shown), arranged such that during a half-cycle of the microwave signal, the beam traverses a 180 degree section of twist.

Claims

1. AN ARRANGEMENT FOR THE CONVERSION OF MICROWAVE ENERGY INTO ELECTRICAL DC ENERGY BY MEANS OR AN ELECTRON BEAM TUBE, COMPRISING MEANS FOR GENERATING AN ELECTRON BEAM TRAVELING ALONG AN AXIS, MEANS TO WHICH THE MICROWAVE ENERGY IS TO BE APPLIED, DISPOSED TO ACT ON SUCH ELECTRON BEAM FOR EFFECTING A COUPLING THEREBETWEEN BY MEANS OF WHICH SUCH MICROWAVE ENERGY IS IMPRESSED ON THE ELECTRON BEAM, SAID MEANS BEING SO CONSTRUCTED THAT THE ELECTRONS UNDERGO, IN ADDITION TO THEIR MOVEMENT IN AXIAL DIRECTION, A RADIAL DEFLECTION OUT OF THE BEAM AXIS, WITHOUT IMPARTING TO THE ELECTRON BEAM ANY MATERIAL VELOCITY DISTRIBUTION, AN ELECTRODE DISPOSED IN THE PATH OF SAID BEAM, FOLLOWING EXIT THEREOF FROM SAID MEANS, FOR BRAKING THE ELECTRON BEAM CARRYING THE MICROWAVE ENERGY, AND A CATCHER ELECTRODE DISPOSED INTHE PATH OF THE ELECTRON BEAM, IMMEDIATELY FOLLOWING THE EXIT OF THE ELECTRONS FROM SAID BRAKING ELECTRODE, AT WHICH THE BRAKED ELECTRONS ARE COLLECTED, AND WHICH FORMS THE OUTPUT ELECTRODE AT WHICH THE ENERGY ORIGINALLY IMPARTED TO THE BEAM IS RECOVERED AS DIRECT CURRENT ENERGY.
