According to the "People's Daily" report, China's total investment of nearly 10 billion hard X-ray free electron laser device project No. 5 experimental well pile foundation started. It is reported that, at present, X-ray free electron laser device has become the developed countries compete for 21st century technology High-tech essential high-tech infrastructure. After the completion of the hard X-ray free electron laser device in Shanghai, it will become one of the most efficient and advanced free electron laser user devices in the world.
Hard X-ray free electron laser device
The total length of the hard X-ray free electron laser device is about 3.1 kilometers. The mission of the project is to build a superconducting linear accelerator with 8GeV energy, 3 undulators lines, 3 light speed lines and the first 10 experimental stations. The device construction includes: Injection , main accelerometer, FEL amplifier (undulator line), light speed line and experiment station, as well as public subsystems including beam diagnostics, control, laser, synchronization, data acquisition and processing, etc., as well as cryogenics, utilities, etc. Supporting systems and facilities.
Filming the movement of molecules, atoms, and electrons
According to reports, the device is similar to a high-speed ultra-clear camera capable of filming molecules, atoms, and electrons. It captures microscopic momentary moving images at high resolution in the femtosecond time, and lets scientists understand the slow motion. Detailed process of complex chemical reactions.
