Definitions
- Th'e'present invention relates to an electric discharge tube of "the type comprising'a'resonant cavity'which is excited around acircular'path-by an electron beam'producedby an annular cath- I 'ode.
- an electric discharge tube comprising a resonant cavity which is excited along a circular path by an electron beam produced by an annular cathode the energy produced is conducted away with the use of a system of concentric conductors which, internally of the resonant cavity, merge into two parallel plates provided with apertures to allow the passage of the electron beam.
- FIG. 1 is an elevational sectional view of the electrode system of a tube according to the invention.
- Fig. 2 is a plan view in section taken on line 11-11 of Fig. 1.
- FIG. 1 an evacuated discharge tube having an enclosing envelope l.
- a system of reflecting electrodes 2 and 3 At the lower end of the envelope is an annular cathode 4.
- plates l0 and II have v is a concentric conductor trodes*5- and '6. interposed between -the-'-beam I reflecting electrodes-2 and' 3, isa resonant'cavity, '1, in the *form of The- "upper-and lower walls of cavity l are each "provided with apertures 8 and -8 respectively, in the shape of segments tr a circle. The various segments 8 or8' are shuntstraps 9; The resonant thereof, "The circularly shaped apertures l2 and I3 respectively. Theseapertures I2 and-l3 ofthe coupling plates are shunted'by strips I4.
- the electrode system 1, l0, II gets a potential of some hundreds of volts positive with respect to the cathode.
- Reflecting electrode 3 gets about cathode potential and reflecting electrode 2 a negative potential.
- cathode 4 and electrode 2 a more or less parabolic field is set up in which the electrons oscillate with constant frequency. Electrons that have lost their energy are deflected to the electrodes and caught by them. The sealing of the tube is explained more fully in Philips Technical Review 8, 257-266, 1946.
- An electric discharge tube comprising an annular cathode for the generation of an electron beam, an electrode in said tube and spaced from said cathode, a cavity resonator interposed between said cathode and said electrode, said cavity resonator having apertures therein for the pas sage of said electron beam, two substantially parallel coupling plates in said cavity resonator arranged with their planes transverse to the path of the said electron beam and each having apertures therein for the passage of said electron beam, and a concentric conductor output system extending out of said cavity resonator, and through said annular cathode at substantially right angles to said parallel plates said concentric conductor system having an inner conductor merged with one of said parallel lates and an outer conductor merged with the other of said parallel plates.
