The X-Ray Tube

Production in Radiography

TermDefinition
X-Rays Produced when high energetic electrons interact with matter.
Atomic The kinetic energy of the electrons is converted into electromagnetic energy by _______ interactions.
Bremsstrahlimg The X-ray tube provides an environment for X-ray production via ______________ and characteristic radiation mechanisms.
X-Ray Requirements: 1. Vacuum 2. Electron Source 3. Target 4. Voltage
Glass Envelope Glass envelope is in the vacuum made of Pyrex glass which is a heat and chemical resistant and is known as a diode because it has two electrons cathode and anode.
Protective Housing Protective device, prevents leakage of x-rays and protects from electrical hazards. Made of lead.
Cathode A negatively charged side as the filaments which is a source of electrons which are made of tungsten it has a focusing cup which in cases coils of filaments focusing cups are negatively charged.
Anode A positively charged is made up of a rotor, stem and target rotor & stem are made of copper because they are heat conductors rotor is shaft like structure that turns stem and target stem attaches target to rotor. Made of tungsten.
Filament
Space Charge Space charges when a group of electrons in the focusing cup move to the target area on to form a cloud.
Thermionic Cloud Thermionic emission occurs when negatively charged electrons break away from hot filament form a space charge.
Focusing Cup
Electron Stream
