On the significance of the invention of accelerator and its influence on human society.

In the process of exploring the properties of microscopic particles, accelerators are the best tools to produce and study various particles. As early as 1930s, e Lawrence (190 1 ~ 1958) invented the cyclotron. China built the BEPC at 1988. CERN's electron-positron collider is the highest energy collider in the world today, with the energy of 100GeV and the circumference of the main accelerator of 27 km. The energy of the large hadron (proton-proton) collider under construction is as high as 16 TeV. ..

The construction of high-energy accelerator benefits from the development of science and technology, such as high vacuum technology, superconducting technology and computer technology. Accelerators play an important role in people's production and life while helping people to further explore the mysteries of the micro-particle world. In the 1940s, electron accelerators were used to treat cancer. Particle accelerators are also used in industrial flaw detection, food preservation and preservation, composite material production and medical supplies disinfection.
