rotating anode. focal track made of tungsten -rhenium which spins on the copper anode rotor and has molybdenum backing because these metals conducts it draws the heat away from the anode. - because the anode is rotating the electrons dont hit at the same spot everytime so the anode does not over heat. focal spot.
- different metal placed between cathode (neg.) and anode (pos.) and created an electron beam by splitting atoms. - came up with charge-to-mass ratio of the electron. -Electrons are particles found in all atoms. -Cathode rays are streams of electrons. **Cathode rays have mass, Matter contains positive and negative charge,Particles of the cathode rays are fundamental to all matter, and An atom is divisible.**.
