X-ray tube assembly continued..
The diagram shows the main internal parts of the assembly.
O :- The entire housing contains oil for its electrical insulating and thermal cooling properties.
N :- A rubber diaphragm allows the oil to expand and contract without increasing the internal pressure.
T: - X-ray tube body is wholly contained in the assembly housing except for the window where the x-rays emerge.
K :- Two cathode heaters are provided. Each have different electron beam properties.
A :- Target anode. The anode in most modern x-ray tubes rotate. This reduces the affect of heating on the anode surface by the incident electron beam.
R :- The rotor and bearings are part of the anode assembly and are fully contained inside the evacuated X-ray tube body.
S :- Stator coils are mounted on the outside of the tube. Their magnetic field drives the rotor and therefore spins the anode when operational.
The image shown on the right is looking into the cathode end of the X-ray tube enclosure
with the cover removed. With the oil drained the terminals and wires connecting the heaters
can be seen on the tube support frame.
The video link shows how the complete unit is disasembled.
