Getters are available in various forms, such as powder, disc, strip, tube, ring, cup, column, etc. Getters are widely used in vacuum electronic devices, creating a good working environment for the devices, stabilizing the characteristic parameters of the devices, and having an important impact on the performance and service life of the devices:

[0003] ① Improve the vacuum degree of vacuum devices in a short time, eliminate residual and re-released gases after the exhaust and sealing of the devices and during the aging process, which is conducive to shortening the exhaust time;

[0004] ②Maintain a certain degree of vacuum during the storage and operation of the device;

[0005] ③ Absorb the sudden gas release of the device during startup and abnormal operation, effectively protecting sensitive components such as the cathode.

[0006] In the prior art, columnar getters mainly rely on columnar surface coating for gas adsorption, that is, the size of the surface area of ​​the columnar getter determines the strength of its adsorption performance; in some cases, the surface of the cylindrical getter is limited and cannot completely adsorb the gas in the device. If the adsorption performance of the columnar getter needs to be increased, the diameter of the columnar getter must be increased, which will cause the volume of the columnar getter to become larger. However, the installation space left for installing the columnar getter is often limited. How to improve the adsorption performance of the columnar getter at the same diameter is an urgent problem to be solved. Utility Model Content

[0011] Preferably, the side surface of the coating portion is wavy, and the wave propagation direction of the wavy side surface of the coating portion is along the circumference of the coating portion.

[0012] Preferably, the side surface of the coating portion is wavy, and the wave propagation direction of the wavy side surface of the coating portion is along the axial direction of the coating portion.
