The X-ray irradiator generates high-energy X-rays to irradiate target objects or biological tissues. The generation of X-rays is usually achieved by accelerating electrons to collide with metal targets (such as tungsten, copper, etc.), generating bremsstrahlung and forming X-ray beams, which then irradiate cells or small animals. X-ray irradiator is used for various basic and applied research. Historically, radioactive isotope irradiators were used, which required transporting samples to a core irradiation facility. However, today, smaller, safer, simpler, and lower cost X-ray irradiator​ can be installed in laboratories for convenient and rapid irradiation of cells. Various samples can be directly irradiated in the laboratory without affecting fertility or safety. The X-ray irradiator is convenient for personnel who have not received professional X-ray training to use, and there are no expensive license applications or safety or radiation source maintenance costs. The X-ray irradiator is easy to operate, safe, reliable, and cost-effective, and can replace radioactive isotope sources. 1.

Safety precautions for X-ray irradiation equipment: Radiation protection: Operators need to wear protective clothing to avoid prolonged exposure to X-rays. Equipment maintenance: Regularly inspect the equipment to ensure its normal operation and prevent radiation leakage. Dose control: Strictly control the irradiation dose to avoid unnecessary harm to the sample or human body.

The principle and application of NDT portable X-ray welding testing machine: NDT portable X-ray welding testing machine is the use of the acoustic, optical, magnetic, and electrical properties of materials to detect the presence of defects or unevenness in the tested object without damaging or affecting its performance. It provides information on the size, location, nature, and quantity of defects. Compared with destructive testing, non-destructive testing has the following characteristics. The first is non-destructive, as it does not compromise the performance of the detected object during testing; The second is comprehensive, as the detection is non-destructive, it is necessary to conduct a 100% comprehensive detection of the tested object, which cannot be achieved by destructive detection; The third is comprehensive, and destructive testing is generally only applicable to the testing of raw materials, such as tension, compression, bending, etc. commonly used in mechanical engineering. Destructive testing is carried out on manufacturing raw materials, and for finished products and in use items, destructive testing cannot be carried out unless they are not intended to continue to serve. Non destructive testing, on the other hand, does not damage the performance of the tested object. So, It can not only perform full process testing on manufacturing raw materials, intermediate processes, and even final products, but also test equipment in service. Characteristics of NDT portable X-ray welding testing machine： The X-ray generator has a small volume, with an anode grounded and forced cooling by a fan; ◆ Lightweight, easy to carry, and simple to operate; Work and rest in a 1:1 ratio; Beautiful appearance and reasonable structure; ◆ Delayed exposure to ensure operator safety; The main purpose of NDT portable X-ray welding testing machine ： The main purpose of the equipment is to inspect the processing and welding quality of materials and components such as ship hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles, and bridges in industrial sectors such as national defense, shipbuilding, petroleum, chemical, mechanical, aerospace, and construction, as well as internal defects and the inherent quality of various light metals, rubber, ceramics, etc.

The X-ray crystal orienter​ operates based on the principle of X-ray diffraction. The high voltage generated by the high-voltage transformer acts on the X-ray tube, producing X-rays. When the X-ray is irradiated onto the sample, diffraction occurs when the Bragg diffraction condition (n λ=2dsin θ) is satisfied. Among them, λ is the wavelength of X-rays, d is the spacing between atomic planes inside the crystal, and θ is the angle between the incident X-rays and the crystal plane. The diffraction line is received by the counting tube and displayed on the microampere meter of the amplifier. When using a monochromator, the diffraction line is monochromatized and then received by the counter and displayed on the microampere meter of the amplifier, thereby improving measurement accuracy. The X-ray crystal orienter can accurately and quickly determine the cutting angle of natural and artificial single crystals (piezoelectric crystals, optical crystals, laser crystals, semiconductor crystals), and is equipped with a cutting machine for directional cutting of the above-mentioned crystals. X-ray crystal orienter is an indispensable instrument for precision machining and manufacturing of crystal devices. The X-ray crystal orienter is widely used in the research, processing, and manufacturing industries of crystal materials. The X-ray crystal orienter is easy to operate, does not require professional knowledge or skilled techniques, displays the angle digitally, is easy to observe, and reduces reading errors. The display of the X-ray crystal orientation instrument can be zeroed at any position, making it easy to display the deviation value of the chip angle. The dual angle measuring instrument can work simultaneously, improving efficiency. The X-ray crystal orienter has a special integrator with peak amplification, which improves the detection accuracy. The integration of X-ray tube and high-voltage cable increases high-voltage reliability. The detector high-voltage adopts DC high-voltage module and vacuum suction sample board, which improves the angle measurement accuracy and speed. Overall, the X-ray crystal orienter is a precision instrument based on the principle of X-ray diffraction, which provides important technical support for crystal material research and related applications by accurately measuring the cutting angle of crystals.
