Provides for control of  line compensation  kVp  mA  exposure time.

a single winding and is designed to supply a precise voltage to the filament circuit and to the high-voltage circuit of the x-ray imaging system

Determines the quality of the x-ray beam

Thermionic emission is the release of electrons from a heated filament. The product of x-ray tube current (mA) and exposure time is (s) is mAs, which is also electrostatic charge (C).

The x-ray tube current is adjusted by controlling the filament current.  Thermionic emission at low kVp and high mA can be space charge limited.

Conducts electricity and radiates heat and x-rays from the target.

High atomic number  Thermal conductivity  High melting point

Molybdenum and Graphite

Lower mass density (lighter)  High melting point

Excessive heat results in reduced x-ray tube life. The most frequent cause of abrupt tube failure is electron arcing from the filament to the enclosure because of vaporized tungsten.
