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 basic research och industriella tillämpningar inom flera discipliner som fysik, kemi, material, information och 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 image" of electrons and record Kvantegenskaper, magnetiska förändringar, kemiska reaktioner och materialfasförändringar relaterade till elektronrörelse .
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, Kinesiska vetenskapsakademi .
Det totala byggområdet för Advanced Attosecond Laser Facility Project är cirka 38, 000 kvadratmeter . Det är konstruerat av China Construction First Engineering Bureau Group Construction CO ., LTD . Konstruktionsinnehållet inkluderar atteSoSecund Device Building, Experimental Center, Experimental Center, Experimental Center, EXCITICAL, PRESITALS, POPROTICEL, POPORT STAT, Power Station, Power Station, Power Station, Power Station, Power Station, Power Stand etc . Raftplattan hälls den här gången är "anti-vibrationssköld" av den extremt exakta ultrafast optiska experimentella plattformen för no . 1 attosekund-byggnaden, som kommer att lägga en solid grund för den efterföljande huvudstrukturkonstruktionen .}
