eXTP is a science mission designed to study the state of matter underextreme conditions of density, gravity and magnetism. Primary goals arethe determination of the equation of state of matter at supra-nucleardensity, the measurement of QED effects in highly magnetized star, andthe study of accretion in the strong-field regime of gravity. Primarytargets include isolated and binary neutron stars, strong magnetic fieldsystems like magnetars, and stellar-mass and supermassive black holes.The mission carries a unique and unprecedented suite of state-of-the-artscientific instruments enabling for the first time ever the simultaneousspectral-timing-polarimetry studies of cosmic sources in the energyrange from 0.5-30 keV (and beyond). Key elements of the payload are: theSpectroscopic Focusing Array (SFA) - a set of 11 X-ray optics for atotal effective area of ˜0.9 m2 and 0.6 m2at 2 keV and 6 keV respectively, equipped with Silicon Drift Detectorsoffering <180 eV spectral resolution; the Large Area Detector (LAD) -a deployable set of 640 Silicon Drift Detectors, for a total effectivearea of ˜3.4 m2, between 6 and 10 keV, and spectralresolution better than 250 eV; the Polarimetry Focusing Array (PFA) - aset of 2 X-ray telescope, for a total effective area of 250cm2 at 2 keV, equipped with imaging gas pixel photoelectricpolarimeters; the Wide Field Monitor (WFM) - a set of 3 coded mask widefield units, equipped with position-sensitive Silicon Drift Detectors,each covering a 90 degrees x 90 degrees field of view. The eXTPinternational consortium includes major institutions of the ChineseAcademy of Sciences and Universities in China, as well as majorinstitutions in several European countries and the United States. Thepredecessor of eXTP, the XTP mission concept, has been selected andfunded as one of the so-called background missions in the StrategicPriority Space Science Program of the Chinese Academy of Sciences since2011. The strong European participation has significantly enhanced thescientific capabilities of eXTP. The planned launch date of the missionis earlier than 2025.
