Barium tungsten cathode has thermal stability to a certain extent, but its stability will be affected by many factors. The following are some factors that affect the thermal stability of barium tungsten cathodes:
Temperature: High temperatures may affect the electron emission performance of barium tungsten cathodes. At higher temperatures, electron emission from the cathode surface may increase, but it may also lead to loss and degradation of the cathode material.
Pyroelectrons: High power electron emission may cause heating of the cathode, generating pyroelectrons. These extra pyroelectrons may interfere with the electron emission properties of the cathode, affecting its stability.
Material properties: The thermal stability of barium tungsten cathode is related to its material properties. High-temperature environments may induce thermal expansion, phase transitions, or lattice defects in materials, thereby affecting electron emission performance.
Application environment: The stability of barium tungsten cathode in different application environments may vary. A vacuum environment may reduce the influence of external factors on the cathode, while in a gas environment it may be disturbed by gas molecules.
Thermal Management: Proper thermal management can help maintain the stability of the barium tungsten cathode. For example, in high power applications, cathode heating may require proper cooling to maintain a stable operating temperature.
