WebThe "ray" is a stream of electrons that naturally pour off a heated cathode into the vacuum. Electrons are negative. The anode is positive, so it attracts the electrons pouring off the cathode. In a TV's cathode ray tube, the stream of electrons is focused by a focusing anode into a tight beam and then accelerated by an accelerating anode. WebThe X-ray tube operates by discharging electrons from a heated cathode directed toward a target or a rotating anode disc, and the point where the electrons strike …
