Soft X-ray Coronagraph on-board ChinesE Space Station (SXCCESS)
Abstract
The solar corona is rich of fine structures, such as coronal holes and polar plumes at high latitudes, and active regions and streamers at low latitudes. More importantly, solar flares, coronal mass ejections (CMEs), and many other types of solar eruptions occur frequently in the corona. The observations of the solar corona can greatly enhance our understanding on these eruptive phenomena and advance the research related to interplanetary space. Meanwhile, the enduring observations can capture some rare phenomena, such as the interaction between comets and the solar wind or between comets and interplanetary CMEs. This type of observations can deepen our knowledge of the solar wind abundance and charge states, the chemical composition of comets. Nanjing University, Beijing Institute of Space Mechanics and Electronics, and China Building Materials Academy jointly propose to develop a Soft X-ray Coronagraph on-board ChinesE Space Station (SXCCESS), in order to conduct unprecedented imaging spectroscopic X-ray observations of the solar corona. With the lobster-eye technique, the telescope can perform imaging spectroscopic observations with a field of view of 1-15 solar radii and a waveband of 0.2-7 keV, which will be a milestone in solar space observations. SXCCESS will provide unprecedented unique data for the solar and space physics communities, and help understanding the trigger/acceleration mechanisms of CMEs and the physics of magnetic reconnection. These observations can also offer space weather forecast for the space environment of the Space Station.
