What you don’t know about the X-ray machine

X-ray machine plays an important role in our daily life. You can find him everywhere. Subway, hospital, airport and so on. It can be said that X-ray machine has become an integral part of our daily life. The X-ray machine [1] is a device for producing X-ray, which is mainly composed of X-ray bulb tube, X-ray machine power supply and control circuit, and the X-ray bulb tube is also composed of cathode filament The X-ray machine power supply can be divided into two parts: high voltage power supply and filament power supply. The filament power supply is used to heat the filament, and the high voltage output end of the high voltage power supply is clamped on both ends of the cathode filament and anode target respectively, providing a high voltage electric field to accelerate the active electrons on the filament to flow to the anode target, forming a high-speed electron After bombarding the anode target, 99% of the energy is converted into heat and 1% of the energy is produced by bremsstrahlung.

X-ray was discovered in 1895 by Professor Renqin of Germany. This kind of radiation line emitted by vacuum tube can penetrate objects. In the electromagnetic spectrum, the energy is stronger than the visible light, the wavelength is shorter, and the frequency is higher. Similar radiation lines include cosmic ray, X-ray, etc.
