Barium tungsten cathodes have several advantages that make them widely used in various electronic devices and applications. The following are some advantages of barium tungsten cathodes:
High thermal stability: Barium tungsten cathode has high thermal stability and can emit electrons stably in high temperature environment, which makes it suitable for high temperature working conditions.
Excellent electron emission performance: Barium tungsten cathode is very sensitive to thermionic emission and can generate enough electrons at a relatively low temperature to form an electron beam.
Long Lifetime: Due to its thermal stability and electron emission properties, barium tungsten cathodes generally have a long lifespan and can maintain stable performance over a period of time.
High vacuum environment adaptability: Many applications require a high vacuum environment, and the electron emission performance of the barium tungsten cathode is excellent in a high vacuum environment.
Electron Beam Steering: The electron emission and beam steering capabilities of barium tungsten cathodes allow the user to adjust the intensity and direction of the electron beam to meet specific needs.
High-brightness electron source: The electron beam generated by the barium-tungsten cathode has high brightness, that is, the number of electrons per unit area is large, making it suitable for applications requiring high-intensity electron beams.
Wide range of applications: Barium tungsten cathodes are widely used in photoelectron spectrometers, TV camera tubes, X-ray tubes, microwave amplifiers and other fields, showing their versatility.
Stability: The performance of barium tungsten cathodes is stable to a certain extent, making them suitable for applications requiring long-term operation and high stability.
High-efficiency conversion: Barium-tungsten cathodes can efficiently convert heat energy into electron energy, thereby achieving high-efficiency electron emission.
