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.
