摘要： In an electron beam tube, such as an IOT, ferrite loaded silicone rubber 30 or some other ferrite loaded dielectric material, is carried by a wall 25 of an input cavity 7. The material absorbs r.f. energy, reducing coupling between different parts of the tube which could otherwise result in undesirable oscillation. Furthermore, its provision on part of the input cavity wall enables easy access to be made for replacement and servicing requirements.

摘要： An electron gun arrangement includes a cathode 1 having a front surface 2 and control grid 3 located in front of it. The control grid 3 is mounted via a cylindrical support 8 on a Kovar mount 12. The cathode 1 is supported by a cylindrical support 6 mounted on a Kovar support 10. Ceramic material 11 being located between the two supports 10 and 12. The vacuum envelope within which the electron gun is contained includes the Kovar support 12 and a flexible member 13 with which it makes a vacuum seal, this member 13 being of copper. The copper member 13 is sealed to a ceramic cylinder 16 via metal flanges 17 and 18. The assembly permits the spacing between the cathode and grid 3 to be maintained whilst the copper member 13 permits thermal expansion to occur to maintain vacuum integrity.

摘要： An electron gun assembly includes a cathode 1, control grid 5 located in front of it and a focus electrode 6. The control electrode 5 is integral with a cylindrical support 11 and formed of pyrolytic graphite. Similarly, the focus electrode 6 is integral with a cylindrical support 16 and is formed of molybdenum. The control grid 5 and focus electrode 6 are mounted on a common mount 15 located behind the front face of the cathode 1, giving a simple structure having low thermally capacity and being mechanically robust.

摘要： In an output resonant cavity 7 used with a linear electron beam tube such as an IOT, magnetic material 17 and 23 is mounted on walls 12 and 13 of the cavity and defines annular channels within which coils 21, 22 and 27 are located to provide focusing of an electron beam travelling along the axis X-X of a tube located in the apertures 15 and 16. An inner rim 28 locates the electron beam tube in relation to the cavity.
