Security X-ray tube is widely used in security inspection of
luggage and vehicles, X-ray irradiation, thickness measurement of
rolled steel plates and many other fields. It is with various focus
combinations and power combinations.
The tube shell of the X-ray tube seals a high-vacuum cavity, and
the anode and the cathode are encapsulated in the cavity, and the
tube shell has sufficiently high mechanical strength and electrical
insulation strength. As the core component of the X-ray tube, most
of the high-voltage electric energy supplied by the high-voltage
generator is consumed as heat, and at the same time it emits a
radiation beam with a dose set by the control system.
The emission mechanism adopted is thermionic emission. The
generated anode electrons are accelerated under the excitation of
high voltage and hit the anode at a very high speed to emit X-rays.
