In this research project, we evaluated the imaging spectral performance of GSENSE6060BSI as a candidate for onboard CMOS for the γ-ray bursting satellite mission. An X-ray spectrum was created from the data obtained by shielding the visible light at room temperature, irradiating X-rays from a sealed radiation source, and obtaining frame data by the photon counting method. The energy resolution of Fe-Kα was 400 eV, and it was found that Fe-Kα and Fe-Kβ had spectral performance that could be discriminated.
