Which component is the tubehead part that enables x-ray exit as its primary function?

The primary function of emitting and allowing x-rays to exit is fulfilled by the x-ray tube. Inside the tube, electrons collide with a tungsten target to produce x-ray photons, and these photons exit through the tubehead window. The tubehead seal mainly serves to seal and contain the insulating oil; aluminum disks filter low-energy photons to reduce patient dose; the lead collimator shapes and confines the beam. None of these other parts generate or provide the exit path for x-rays, so the tube itself is the component whose main job is to enable x-ray exit.
