The structure of the barium tungsten cathode has an important influence on its performance, especially for electron emission performance and stability. The following are some factors that affect the performance of the barium tungsten cathode structure:
Surface morphology: The morphology of the cathode surface can affect electron emission efficiency. A smooth surface reduces collisions of electrons with the surface, thereby improving emission efficiency.
Barium content: The addition of barium can significantly affect the electron emission performance. Adding an appropriate amount of barium can reduce the work function of the cathode, making it easier for electrons to escape, thereby improving the emission efficiency.
Purity: The purity of the cathode material is also very important to performance. Impurities and impure substances may affect electron emission characteristics, reduce emission efficiency and affect stability.
Emission Area Design: The emission area design of the cathode can affect the uniformity and intensity distribution of electron emission. Proper emission area design can achieve more uniform electron emission and thus improve performance.
Preparation process: The preparation process of the cathode will also affect its performance. The choice of process parameters, such as sintering temperature, cooling rate, etc., will affect the crystal structure and morphology of the cathode.
Thermal stability: The stability of barium tungsten cathode in high temperature environment is also related to its structure. Reasonable structural design can maintain the stability of electron emission performance in high temperature environment.
