Abstract
To investigate the density of the upper atmosphere at ~100 km by X-ray observations of the cosmic X-ray background (CXB) through the Earth rim, we are developing a specialized instrument for this purpose. It consists of a slit collimator and SOI-CMOS sensors and is planned to be installed on the International Space Station (ISS) in 2025. In this talk, we study the feasibility of the observations by considering the attitude fluctuation of the ISS and the particle background in orbit and estimate that the observation efficiency of the CXB is about 70%.
