摘要 |
An X-ray tube has a control grid located to cover a filament which is insulatingly mounted on a first focusing electrode. The control grid is electrically connected to the first focusing electrode. A second focusing electrode is so mounted on the first focusing electrode through an insulator that it covers the control grid. The second focusing electrode is made at the same potential level with that of the filament.
