GECAM: a new SPPSS-II mission in 2020, a new all-time and all-sky X/gamma-ray monitor in multi-messe

The First GW with gamma-ray and X-ray multi-wavelength electromagnetic emission from binary Neutron Star merger was known as a historical milestone in physics and astronomy, and made a global hot campaign in multi-messenger/wavelength ear. Here we introduce a new all-time and all-sky X/γ-ray monitor, named GECAM telescope, which is a new China space science program. It is the first mission of opportunity in the Strategic Priority Program on Space Science (SPPSS-II), Chinese Academy of Sciences. To better and timely monitor the random all-sky 6 keV - 5 MeV X/γ -ray emission that associated with GW sources, FRBs, TGFs. Etc. GECAM was designed as two satellites that run on both sides of the earth, and each of the satellite on-borad 25 Gamma-ray detectors of LaBr3+SiPM frame and 8 Charged particle detectors of Plastic scintillator+SiPM frame. Furthermore, with an on-orbit trigger and real-time alarm system, the mission would transmit alerts data to ground scientific center within several minutes. The satellites plan to launch by the end of 2020, and complete the in-orbit test, By then, it will open to global scientists and researchers. Welcome to the mission and sciences, joint observations. etc.
