| titleOfInvention | Cathode arrangement for an electron tube and such an electron tube |
| abstract | The electron tube has an electron emitter (4) which is indirectly heated by means of a heating device (5). The heating device (5) includes an infrared radiation source (6) and an associated optical element. The optical element is formed such that it collects infrared radiation from the source (6) from a spatial angle (alpha) and directs it to the emitter. The angle (alpha) from which the optical element collects the radiation is greater than the angle (alpha) from which infrared radiation would be incident on the electron emitter (4) without the optical element. The optical element preferably includes a reflector with e.g. a gold coated reflective surface. |
