Abstract
We report on the background study of the CCD camera of the MAXI mission on-board the International Space Station. Our study is based on the simulation using the Geant4 toolkit. We studied the background from cosmic electron in 3-100MeV range mainly. Our result shows that the design of collimator and slit is important to reduce the X-ray background (mainly bremsstrahlung). Thick collimator and slit is preferable. Material is also important.
