Final answer:
The component in an intensification tube that absorbs electrons and emits light photons is the (2 )output phosphor. Similar processes in CRTs and high-voltage tubes can result in X-ray production.
Step-by-step explanation:
In an intensification tube, the component that absorbs electrons and emits light photons is the output phosphor. When electrons come into contact with the output phosphor, they are converted into visible light photons, allowing for the creation of images. This is similar to the process in some older television tubes, which are cathode-ray tubes (CRTs), where an accelerating voltage stimulates phosphors to emit light to form images.
Moreover, in these high-voltage environments, there is a potential for x-ray production when electrons strike certain materials. For example, when an electron is accelerated in a tube by a high positive voltage and strikes a metal plate, it can produce X-rays. This is indicative of the electron obtaining enough energy to ionize the atom.
