What part of the X-ray machine is responsible for housing the electrons?

The part of the X-ray machine responsible for housing the electrons is the cathode. In an X-ray machine, the cathode is made up of a filament and a focusing cup. When the filament is heated, it emits electrons through a process called thermionic emission. These electrons are then directed toward the anode, where they collide and produce X-rays.

Understanding the role of the cathode is crucial as it is the starting point of the X-ray generation process. The electrons produced here are essential for creating high-energy photons, which are then emitted as X-rays when they interact with the anode's target.

In contrast, the anode is where the electrons hit to produce X-rays, while the filament serves a specific function of electron generation within the cathode. The term "canode" does not pertain to standard X-ray machine terminology and is likely a misnomer.
