The Advanced Attosecond Laser Facility, a major national scientific and technological infrastructure, has made important progress. The first raft slab of the No. 1 Attosecond Device Building was cast a few days ago. This is the world's second large attosecond laser scientific facility. After completion, it will provide strong support for frontier Grundlæggende forskning og industrielle anvendelser inden for flere discipliner såsom fysik, kemi, materialer, information og biomedicin .
Attoseconds are the shortest time scale that humans can currently master. With the help of attosecond laser pulses generated by advanced attosecond laser facilities, scientists can "shoot" the instantaneous process of high-speed moving electrons. The advanced attosecond laser facility is like an "ultra-high-speed camera" that can capture the "dynamic Billede "af elektroner og registrering af kvanteegenskaber, magnetiske ændringer, kemiske reaktioner og materialefaseændringer relateret til elektronbevægelse .
The advanced attosecond laser facility has a total of 10 beam lines and 22 application terminals, and is planned to be completed in 5 years. The 6 beam lines built in Dongguan are under the responsibility of the Institute of Physics, Chinese Academy of Sciences, and the other 4 beam lines will be built in Xi'an, Shaanxi, under the responsibility of the Xi'an Institute of Optics and Precision Mechanics, Chinese Academy of Sciences .
The total construction area of the Advanced Attosecond Laser Facility project is about 38,000 square meters. It is constructed by China Construction First Engineering Bureau Group Construction Development Co., Ltd. The construction content includes the attosecond device building, experimental center, precision optical mechanical processing center, power station, power station, osv. . Raftpladen, der hældes denne gang, er "Anti-Vibration Shield" i den ekstremt præcise ultrahastede optiske eksperimentelle platform for NO . 1 Attosecond-enhedsopbygningen, som vil lægge et solidt fundament for den efterfølgende hovedstrukturkonstruktion .}
