X ray and laser coaxial system

Abstract

The invention relates to an X ray and laser coaxial system. The X ray and laser coaxial system comprises an ionization chamber adjusting device and a laser adjusting device; the ionization chamber adjusting device comprises a first track which is parallel to an X ray; the beam center of the X ray and the center of an array flat-panel detector are overlapped; the laser adjusting device is located at a corresponding position of one side of the ionization chamber adjusting device; a laser which is used for emitting a laser is clamped by the laser adjusting device; when the laser irradiates on the array flat-panel detector, the laser emergent position of the laser is adjusted to enable the cross center of the laser and the center of the array flat-panel detector to be overlapped; the relative distance of the array flat-panel detector and the laser adjusting device is changed and the laser emergent position of the laser is adjusted again to enable the cross center of the laser and the center of the array flat-panel detector to be overlapped again; the laser emergent position of the laser is adjusted to until the cross center of the laser and the center of the array flat-panel detector to be always overlapped so as to enable the laser and the X ray to be coaxial. According to the X ray and laser coaxial system, the coaxial treatment on the X ray and the laser is convenient to achieve.

[0002] The X-ray standard radiation device is used in the verification, calibration and detection of X-ray radiation instruments, as well as in the fields of industrial non-destructive testing, but the existing equipment cannot realize the adjustment of the X-ray main beam axis direction, or the adjustment process is complicated and difficult to achieve The coaxiality of the main axis of the X-ray beam, the center of the beam-limiting diaphragm and the positioning device (positioning laser line) of the radiation instrument is difficult to achieve, especially when the positioning device is placed on a long guide rail with a variable stroke, so that it cannot be guaranteed The detector center of the inspection equipment is in the center of the X-ray beam, and it cannot be ensured that it is in the uniform radiation field; at the same time, most of the existing equipment is locked, and it is not suitable to disassemble after adjusting the beam and fixing the X-ray tube, and it is difficult to reset , and this method is difficult to reset after the position is changed due to vibration, collision and other reasons during use; at the same time, the filtering adjustment of the X-ray beam radiation quality in the prior art usually adopts a manual switching method. Faster conversion cannot be achieved. Moreover, most laboratories have an X-ray tube equipped with an additional filter turntable. When using more radiation beam specifications, it is necessary to disassemble the filter turntable and other operations, which is very inconvenient. Some solutions That is to configure more X-ray machines, so that the laboratory space, control equipment and other existing equipment are not fully utilized
