Retrieval of damaged fuel debris at the Fukushima Daiichi Nuclear Power Station is expected to generate a variety of radioactive particles such as powder debris and aerosol particles caused by laser cutting. To prevent radiation exposure to workers and environmental pollution, it is important to clarify the dynamics and composition of the radioactive particles. For the on-site real-time measurement of radioactive particles, we have been developing a single particle mass spectrometer. In this study, we have conducted the performance evalua- tion of the developed particle focusing and sizing region.
