Problems solved by technology

[0003] The technical defect of this kind of X-ray tube when it is used as irradiation is: the main axis of the ray exit direction is 90 degrees to the electron beam, and its effective irradiation angle must be less than 2 times the target angle, generally the maximum is about 40 degrees, which cannot be expanded. It is used in industry No problem for X-ray imaging, but for irradiation, the irradiation area is significantly reduced
However, it is used exclusively for irradiation, and there are still defects such as low maximum power and low cooling efficiency.

Embodiment

[0043] figure 1 It adopts corrugated ceramic vacuum sealing shell, the cathode emitter adopts indirect heating plane emitter, and the anode target and exit window adopt a protruding arc surface and a radiation-specific transmission type direct water-cooled anode super-large focus X-ray tube with corrugated structure Examples (see figure 1 ). This embodiment includes an anode assembly 2, a cathode assembly 4, an insulating corrugated ceramic vacuum package shell 5, and an anode water cooling jacket 3 outside the vacuum package. The outer end of the anode assembly 2 has a transmissive anode target sheet 1, the front end of the cathode assembly 4 is not provided with a conventional X-ray tube cathode focusing bowl, but is provided with a large-area emitting cathode sheet 6, and the outer end of the anode water cooling jacket 3 An exit window 7 is provided in the center of the part. The mutual structural relationship is: the anode target sheet 1, the large-area emission catho...

Abstract

The invention discloses a special transmission-type direct water-cooling anode super-large focus X ray tube for radiation. The X ray tube comprises an anode assembly, a cathode assembly, an insulating ceramic vacuum packaging housing and an anode water-cooling jacket arranged outside the insulating ceramic vacuum packaging housing. The special transmission-type direct water-cooling anode super-large focus X ray tube for radiation has the advantages of high radiation conversion efficiency, high radiation intensity, large radiation angle, good radiation uniformity and the like, and can be assorted with a high-voltage power supply so as to replace a radioactive nuclear radiation source in the radiation industry, so that the dependency on the nuclear radiation source can be finally and completely eliminated, and the potential threat of releasing radioactive nuclear pollution to environment can be eliminated.

Description

technical field [0001] The invention mainly relates to a transmission-type direct water-cooled anode super-large-focus X-ray tube dedicated to irradiation, and belongs to the technical field of ionizing radiation irradiation equipment. Background technique [0002] Utilizing the strong penetration of ionizing radiation and the biological effect of radiation dose on organisms, human beings have widely used nuclear radiation technology since the last century with the slogan of peaceful use of nuclear energy, such as: food preservation, article disinfection, sterilization and insecticide , Irradiation biological effect research, blood product processing (to prevent blood transfusion reaction) and other various application fields have also achieved great social and economic benefits, and nuclear radiation sources for irradiation are therefore widely used. Due to the uncontrollable characteristics of nuclear radiation, nuclear radiation sources have been producing radiation to th...
