We have developed the secondary electron emission (SEE) with wide energy range for spacecraft thermal control materials. SEE yield measurement is very important for analyzing charge accumulation on the spacecraft surface. Therefore, we are developing the measurement system without the deceleration voltage and enable to obtain the characteristics of the SEE yield on those materials irradiated by an electron beam with energy of 200 eV to 10 keV. Furthermore, SEE yield on the aging materials is also important for determination of end of life of spacecraft. 50 keV electron gun for aging was attached on the developed chamber, we can create the seamless system form the aging to SEE measurement.
