Detailed explanation-1: -X-rays are generated via interactions of the accelerated electrons with electrons of tungsten nuclei within the tube anode. There are two types of X-ray generated: characteristic radiation and bremsstrahlung radiation.

Detailed explanation-2: -The cathode is part of an x-ray tube and serves to expel the electrons from the circuit and focus them in a beam on the focal spot of the anode. It is a controlled source of electrons for the generation of x-ray beams.

Detailed explanation-3: -In the Coolidge tube, the electrons are produced by thermionic effect from a tungsten filament heated by an electric current. The filament is the cathode of the tube. The high voltage potential is between the cathode and the anode, the electrons are thus accelerated, and then hit the anode.

Detailed explanation-4: -The filament is a coiled tungsten wire that is the source of electrons during x-ray production. FIGURE 2-1 Most x-ray tubes use a small filament and a large filament, corresponding with a small focal spot size and a large focal spot size, respectively. The filament is the source of electrons during x-ray production.

Detailed explanation-5: -Tungsten has a high melting point and generates X-rays when irradiated with a high-speed electron beam. Because of these properties, it is used as an X-ray source for various X-ray tubes used in medical and security devices.
