At CERN, Geneva, Professor Samuel Chao Chung Ting from the Massachusetts Institute of Technology recently announced that AMS02 would take the American space shuttle STS-134 of “Endeavour” and lift off on 7:30 a. m. EDT, July 29th, 2010 in Kennedy Space Center, USA, heading to the International Space Station for a three year mission.

　　The electromagnetic calorimeter, known as the second stage project of The Alpha Magnetic Spectrometer experiment (AMS02) weighs 6,700 kilograms. The physics goals of AMS02 are to search for antimatter and dark matter in the universe and precisely measure the ingredients of various isotopes in the universe. AMS02 was developed by IHEP scientists in collaboration with their colleagues from the Chinese Academy of Launch Vehicle Technology (CALVT), Italy and France. It can measure electron and photon up to 1 TeV;

　　At present, the assembling of AMS02 was completed. It will first undergo the beam test at CERN, and then the thermo vacuum test in simulated space environment at European Space Research and Technology Centre (ESTEC)，Holland. In early next year, AMS02 will be sent to Kennedy Space Center to be installed in the space shuttle. With the statistics accumulated within a short time right after lifting into the space, AMS02 will surpass the running PAMELA, for having more precise and broader measurement of the energy distribution of antiproton, positron and photon in outer space.

　　For a very long time in the future, AMS02 will be extremely important for detecting new physics phenomena and searching for super symmetric particles. The scientific community is anticipating the significant physics accomplishments from AMS02.
