Cosmic-ray background simulation for the CCD camera (SSC) of the MAXI mission onboard the International Space Station
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.
