The classical X-ray tube 

The academic X-ray tube requires: 

*  electron acceleration potential

* goal for X-ray production

*  electron source 

The foremost constituents of the modern X-ray tube are:

*  anode (acceleration potential)

*  cathode (electron source)

*  vacuum tube (metal)

*  target device

 (A) anode

 (K) cathode 

 (Uh) cathode voltage

 (Ua) anode voltage

Usual operation situation are:

* Electron present: 1 to 5 mA (for relentless operation)

* Electron present: 0.1 to 1.0 A (for short exposures)

*  Acceleration Voltage: 20 to 150 kV 

• The anode is a untainted metal.( Fe,Cu,Co..)

• The tube is chilled by water and housed in a protecting aluminum tower
