Title: Improvements in or relating to electron tubes of the travelling-wave tube type
IPC: H01J25/36
Filed: 1954-09-22
Abstract: 766,724. Travelling wave tubes. SIEMENS & HALSKE AKT.-GES. Sept. 22, 1954 [Sept. 22, 1953], No. 27422/54. Class 39(1). A travelling wave tube comprises means for projecting one or more electron streams successively through a first slow wave structure 5, in which the electrons induce and sustain waves of negative phase velocity, and a second slow wave structure 7 in which is produced an increasing wave of positive phase velocity by the modulated electron stream or streams, there being substantially no coupling between the slow wave structures except that due to the electrons. The delay lines 5, 7 may be helices (as shown), folded lines, spirals, or each may be a combination of different types of structure, and the beam is annular (as shown), cylindrical or flat. The beam may travel inside 5 and outside 7 (as shown) or outside 5 and inside 7. Decoupling of the two helices is achieved by loss material 6 which may be a coating of carbon or of ferromagnetic material on the right hand end of 5 and on the left hand end of 7 and/or by the provision of one or more electrode diaphragms between 5, 7. A load or matched loss is provided at the left hand end of 5. The main output is taken from 7 by a coaxial line (not shown) to load 11. Helix 5 is essentially dispersive, the circumference per turn being equal to # or less than # and helix 7 is made non-dispersive. The voltage V<1> of helix 5 can be varied for tuning or can be alternating or D.C. with superimposed A.C. to give a frequency modulated output from 7. The invention can also be applied to tubes having crossed electric and magnetic fields both for the oscillating system 5 and for the amplifying system 7. In this case tuning is accomplished by varying the transverse electric field.
