After a rigorous and comprehensive inspection and acceptance, the technical expert group first started the commissioning of the free electron laser amplifier. After more than one hour of intense waiting, high-quality electron beams exceeding 300 megavolts of energy finally passed through the free electron laser amplifier. All components, the 18-meter-long undulator array emitted the first extreme ultraviolet light, which won the applause of the field staff.
The Dalian coherent light source is the subject of the project “Comprehensive Experimental Device Based on an Adjustable Extreme Ultraviolet Coherent Light Source†funded by the National Natural Science Foundation of China. This bunch of EUV light is the strongest EUV beam in the world, and each laser pulse of the light source can Send more than 10 trillion photons, the wavelength can be continuously adjustable from 50nm to 150nm, with complete coherence, pulse length can choose between femtosecond and picosecond mode. This light source has an extremely wide range of applications in important scientific fields such as chemistry, physics, biology, energy, materials, and the environment.
[China Instrument Network Instrument R&D] Recently, learned from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, the world’s only free electron laser user device working in the extreme ultraviolet region is also the first free scientific user device of the free electron laser—Daqing Cogan After persistent exploration and pursuit, the light source was finally installed.
