OEM/ODM Manufacturer Copper Tungsten Tube - E-Beam Filament 7.5turns – WINNERS Detail:

Product Description

The choice of materials has a decisive influence on the emission ability and life of the electron gun. Filament must be made of high melting point and high resistivity material, generally made of tungsten wire. After passing through the strong current, the filament is heated to more than 1000 degrees.
The cathode must be made of a low work function material. The outer electrons of the atoms on the cathode surface, after being excited by a certain amount of heat or electrical energy, will detach from the nucleus and become free electrons. Tungsten wire is selected as the material, and its work function is 4.55 electron volts.
