X-RAY TUBE-DRIVING ELECTRONS

1. Two sources of electrical energy are required by the tube - filament heating voltage (~10 V) and current (~10 A).
2. Accelerating voltage (typically 30 - 150 kV) also known as the tube voltage or kV.
3. The flow of electrons between the cathode & anode generates a tube current or mA (typically 0.5 - 1000 mA).
