ELECTRON TUBE WITH A CESIUM SOURCE |
| 摘要 |
In an electron tube based on a cold cathode, a cesium source (17) containing Csx-Auy or Csx-Sby is provided near the cold cathode (7), preferably in contact with the first grid (9). Cesium is introduced into the source during activation of the tube. The vapor pressure of the cesium compounds is such that proper delivery of cesium is guaranteed throughout the life-time of the cathode.
