Description
Laser acceleration is a new kind of acceleration technology, which uses the plasma accelerating particles generated after the interaction of ultra-high power laser and matter. Because the plasma does not have the breakdown problem, the plasma acceleration method can provide an acceleration gradient three orders of magnitude higher than the traditional acceleration method. The use of laser acceleration technology is expected to greatly reduce the scale of high energy accelerator, which is a very promising new acceleration technology. Laser acceleration technology is an international research hot spot, there are many research teams in this area of research, and achieved very meaningful experimental results. Lawrence Berkeley Laboratory in the United States, using laser electron acceleration technology, using 1 cm of discharge capillary, obtained 1 GeV of high-energy electrons. Korea accelerate protons and obtained 93 MeV high energy protons. The application of laser acceleration technology in the field of cancer treatment is an important research content of laser acceleration device in the world. Peking University began to study laser acceleration technology in 2006, and proposed a method of radiation pressure acceleration, which can make more efficient use of laser energy and obtain higher proton energy. In 2017, the first laser accelerator prototype in the world was built, and in 2019, the development of a laser-accelerated proton cancer treatment device was started. The report will introduce the relevant research progress of laser acceleration technology in the field of cancer treatment and other fields.
