Step 1

Accelerated / fast moving electrons

Answer

X-rays are produced when electrons are accelerated to high speeds. This acceleration is typically achieved through the use of a high-voltage electrical source within an X-ray tube. The electrons gain significant kinetic energy as they are forced through a vacuum.

Step 2

Strike a (heavy) metal (target) anode

Answer

Once the electrons are moving rapidly, they are directed towards a heavy metal target, often referred to as the anode. Upon striking this target, the kinetic energy of the electrons is converted into X-ray photons. This process involves both bremsstrahlung (braking radiation) and characteristic radiation, depending on the interaction of the electrons with the target material.
