Coolidge Tube Function and Properties

The video tutorial explains the production of x-rays using a Coolidge tube, which consists of a highly evacuated glass bulb with a tungsten filament cathode and a metal anode. Electrons emitted from the heated cathode are accelerated towards the anode, producing x-rays upon impact. The setup includes a Melinda gnam cylinder to focus the electron beam and a copper block for heat dissipation. The intensity of x-rays can be controlled by adjusting the current through the filament.

What is the primary function of the Coolidge tube in x-ray production?

• To store x-rays

• To generate x-rays
