Functional principle
1. The x-ray tube generates the primary x-radiation (primary radiation). The electrically
heated cathode emits electrons. Accelerated by the applied high voltage to very high
speeds, the electrons bombard the anode material. This generates the primary
x-radiation.
2. The primary filter optimizes the energy distribution of the primary x-radiation.
3. The shutter serves as a safety device and closes the access of the primary x-radiation
to the measurement chamber, if needed.
