X-ray Tube

Question 1

Cathode

Answer 1

Made of tungsten filament and molybdenum cup; NEGATIVE charge

Question 2

Anode

Answer 2

Made of copper arm and focal spot

POSITIVE CHARGE

Question 3

Cathode properties

Answer 3

Filament: heated to give off a cloud of electrons; thermionic emission
Cup: focused electrons toward anode
Supplies the electrons necessary to generate x-rays

Question 4

Anode properties

Answer 4

Focal spot made of tungsten (target = tungsten) converts bombarding electrons into x-ray photons
