X-ray Image Intensifiers

Structure & Principle of operation

X-ray image intensifiers comprise an input screen, a photocathode, a focusing electrode, an anode and an output screen, housed in a vacuum envelope.
Photoelectrons converted from X-rays are accelerated by high voltage and focused by an electronic lens comprising a focusing electrode and an anode, and project an image on the output screen.
