What Is the Use of Tungsten Wire in X-Ray Equipment?

Tungsten wire has an important use in X-ray equipment, mainly used to manufacture X-ray tubes. The following are the functions and applications of tungsten wire in X-ray equipment:

Cathode: Tungsten wire is usually used as the cathode of the X-ray tube, which is the electron emitter. In an X-ray tube, a tungsten filament is heated and thermionic emission is produced by electron flow. These hot electrons are focused into electron beams in the vacuum environment inside the tube, and then hit the target through the anode, thereby producing X-rays.

Electron emission: Tungsten is an excellent electron emission material because its electron emission performance is very stable and it can continuously emit electrons at high temperatures. This is very important for the stability and continuity of X-ray equipment.

High Temperature Tolerance: Tungsten filaments are able to withstand high temperatures, which is critical to generating enough heat in an X-ray tube to create a flow of electrons.

Long life: Tungsten filaments generally have a long service life, which means that the X-ray tube can continue to be used for a long time without the need for frequent cathode replacement.

Stability: The electron emission performance of tungsten wire is very stable and can provide a consistent electron flow to ensure the imaging quality and performance of X-ray equipment.
