The Division is mainly involved in studies of the large-scale structure and evolution of the universe by observing cosmic rays. The Division undertakes many important research projects and international collaborations.
The Hard X-ray Modulation Telescope (HXMT) is a collimated hard X-ray (20-200 keV) telescope with the highest sensitivity and spatial resolution power in the world. Its R&D started in March 2011, and will be launched in 2015.
The Large High Altitude Air Shower Observatory (LHAASO) Project will be the best high altitude cosmic ray observatory in the world. It has been approved as one of the key national scientific and technological projects and will focus on the origin of cosmic rays.
The Division has taken part in China’s lunar exploration project, the Chang'e I, II and III, and has made important contributions.
The Division is very active in international cooperation. It hosts the Sino-Japanese ASγExperiment and the Sino-Italian ARGO Experiment in Tibet, and has joined the AMS International Collaboration at CERN, etc.
