Treating eye cancer without damaging vision is a magical treatment effect of medical proton accelerators. On December 6, China's first medical high-energy high-flow proton cyclotron production and R&D base broke ground in Haiyang City, Shandong Province. The medical proton accelerator is introduced from France by Haiyang Emma Accelerator Manufacturing Co., Ltd., aiming at promoting the application of non-power nuclear technology in China, filling China's nuclear energy, nuclear medicine, nuclear medicine, radioisotope diagnosis and treatment, etc. A blank in the field.
It is reported that the accelerator can produce high-quality proton beam, which will be mainly used for radiation therapy of tumors. Protons enter the human body at a very high speed, and the damage to the normal tissues or cells of the human body is far lower than that of the currently used X-rays. The treatment accuracy is within 0.1 mm, which is a magic weapon for treating eye diseases. At the same time, the energy carried by protons into the human body is significantly higher than that of X-rays, so the radiotherapy effect of protons is better than X-rays.
It is reported that the current number of medical accelerators per million population is only 0.38 in China, far below the level recommended by the World Health Organization. The medical accelerator has great potential in China. After the project is completed, it is expected to produce 12 proton strong current accelerators per year. ——Shanghai Medical Device Industry Association
A spectrometer is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors. Spectrometers were developed in early studies of physics, astronomy, and chemistry. The capability of spectroscopy to determine chemical composition drove its advancement and continues to be one of its primary uses. Spectrometers are used in astronomy to analyze the chemical composition of stars and planets, and spectrometers gather data on the origin of the universe.
Examples of spectrometers are devices that separate particles, atoms, and molecules by their mass, momentum, or energy. These types of spectrometers are used in chemical analysis and particle physics.
