• Steps in the x-ray production process in a rotating anode x-ray tube

  1️⃣ Emission of electrons from the cathode

  2️⃣ Acceleration of electrons towards the anode

  3️⃣ Collision of electrons with the tungsten disc

  4️⃣ X-ray generation

  5️⃣ Heat dissipation by the rotating anode
• Match the component of a rotating anode x-ray tube with its role in x-ray production:

  Cathode ↔️ Emits electrons

  Anode ↔️ Generates x-rays

  Stator ↔️ Rotates the anode
