On May 17, the Institute of High Energy Physics, Chinese Academy of Sciences and Springer Nature jointly released a major discovery-the National Major Science Infrastructure High Altitude Cosmic Ray Observatory (LHAASO) discovered a large number of ultra-high energy cosmic accelerators in the Milky Way, and recorded a maximum of 1.4 Beat electron volts gamma photon (beat = peta billion).

  Through the drone lens, the high-altitude cosmic ray observatory covering an area of ​​1.36 square kilometers is like a copper coin placed among the mountains.

Scientists call him "Brother Kong Fang".

It is a one-square-kilometer ground shower particle array (KM2A for short) composed of 5195 electromagnetic particle detectors and 1188 muzi detectors, 78,000 square meters of water Cherenkov detectors, and 18 wide-angle Cherenkov telescopes staggered The composite array composed of the arrangement adopts four detection technologies to measure cosmic rays in an all-round and multi-variable manner.

  It is reported that LHAASO, with cosmic ray observation as the core, is located in Haizi Mountain at an altitude of 4410 meters in Daocheng County, Sichuan Province. It is expected to be completed in 2021, realizing a full array of scientific observations.
