Linear motor platform "Hard X-ray free electron laser device". On April 27, the "hard X-ray free electron laser device" construction started. This marks the country’s largest investment in the country’s major science and technology infrastructure projects so far – the hard X-ray free electron laser device has since entered a period of comprehensive construction.

     Its world-leading photonics science center, which is composed of the Shanghai synchrotron light source, soft X-ray free electron laser device, and ultra-short ultra-short laser experimental device, will enable China's photonics scientific research to lead from parallelism to parallelism. .

     It is understood that the construction of the hard X-ray free electron laser device is located in the core area of the Zhangjiang Comprehensive National Science Center in Shanghai. The total length of the device is about 3.1 kilometers. An underground tunnel with a depth of more than 30 meters will be built, including a superconducting linear accelerator tunnel and undulators. 10 tunnels and 5 working wells such as tunnels and beamline tunnels.

     Hard X-ray free electron lasers have higher brightness, shorter pulse structure, and better coherence. They can provide higher X-ray peak brightness than third-generation synchrotron radiation sources. With nano-class ultra-high spatial resolution and femtosecond ultra-fast time resolution. In addition, X-ray free electron lasers can increase the ability to study the microscopic world from taking “molecular photographs” to filming “molecular film” levels, as well as meeting material-oriented, single-molecule, super-ultra-short single-particle imaging, and extremes. Optical physics and other needs of multiple experimental stations.

     This large-scale user device will enable scientists to understand the structure-activity relationship of the material system over a large time span (seconds to sub-femtoseconds), space scale (microns to angstroms), and in-situ environment, providing the most advanced all-power spectrum, multi-dimensionality , non-linear, coherent X-ray material characterization methods, and provide users with the ability to observe and control the structure of a substance and its dynamic processes at the molecular, atomic, and extreme conditions to reveal life mechanisms, regulate chemical reactions, and explore quantum control And other national strategic technology major issues to provide solutions.

     The Tongmao linear motor platform uses a highly efficient ironless linear motor as a drive component. Our direct drive platform has high speed, high acceleration and stable accuracy. Compared with the screw drive, the structure is more compact and more efficient. The linear motor platform provides a satisfactory system solution for applications that require high throughput, high reliability, precision positioning, and silent operation.
