In a x-ray tube, there are two main structures: the filament and the anode. To generate x-rays, electrons need to interact with a material with high atomic number, as they can thus manipulate the trajectory of flying electrons easier, and also allow for more electron-electron interactions to occur (because in comparison, low atomic number = less attractive force from the nucleus and generally less electrons as well). The higher melting point is required because the ...
