Abstract

541,631. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. June 7, 1940, No. 9976. Convention date, June 15, 1939. [Class 39 (i)] Electron discharge apparatus for use as a detector, amplifier, oscillation generator &c. comprises means for providing a magnetic field, a beam of electrons in the direction of the magnetic field and having velocities transverse thereto and a transverse highfrequency electric field, whereby the beam of electrons is separated into two groups having differing transverse velocities. Means, such as a diaphragm electrode, or a reflecting electrode allow a selected group to pass through a further transverse high-frequency electric field for the abstraction of energy from the beam. Preferably the beam of electrons originates from an annular cathode and is formed into a cone by a focusing electrode . Apparatus embodying the invention is shown in the drawing. An envelope 50 has a tubular body part with two pairs of oppositely disposed arms 51, 52 and 53, 54. Sleeves 61, 62 are disposed across the pairs of arms and have aligned apertures 64... 67. Dielectric guides, such as 56 are sealed to the ends of the arms by insulating members 57 with a partition 59 and internal conducting coating 60. A circular thermionic cathode 69,, shield 70 and diaphragm 71, electrically connected and mounted on the sleeve 61 in abutment with the apertures 64...67, provide the beam of electrons along the direction of the magnetic field represented by pole pieces 80, 81. A tubular electrode 68 mounted in the tubular part of the envelope, reflects one group of electrons, and the other group is collected by the electrode 77. The incoming signal, represented at 82, sets up a high-frequency electric field across the sleeve 61 ; and the output signal is transmitted at 83. The device may be tuned by reflecting pistons 84, and feed-back coupling obtained by the Lechner wires 86, or by a second beam of electrons transversing the envelope in the reverse direction.
