Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
The electrons emitted from the filament are converged by the focusing action of the cathode 3 to form an electron current, and the converged electron current is applied to the anode target at a high speed under the action of a high voltage of the anode 4 to generate x-rays, which are output from the x-ray output window 210. The die 2 encloses the cathode 3, the anode 4 and the x-ray output window 210 together to obtain a high vacuum by evacuation so as to obtain a good withstand voltage, and a high voltage generated by a high voltage power supply is transmitted to the anode 4 of the x-ray tube through a high voltage cable and a high voltage socket 6.
the thickness of lag 8 is 2mm, and the material of lag 8 is the lead sheathing.
the whole inner side wall of the shell 1 is embedded with a lead plate 5.
the thickness of the lead plate 5 is 2 mm.
a gap is formed between the outer wall of the tube core 2 and the inner wall of the shell 1, and transformer oil is injected into the gap and used for high-voltage insulation and heat dissipation.
Example 6, as shown in fig. 1, this example is a further optimization performed on the basis of example 6, and specifically includes the following steps:
the housing 1 is made of stainless steel, which can prevent leakage of x-rays to some extent.
