We have newly developed a proton-beam irradiation system driven by a high-intensity laser for biological studies. In the laser-ion acceleration, X-rays and electrons are generated simultaneously with the protons. In order to remove them, we equiped a magnetic analyzer in the irradiation system. Moreover, we developed a cell capsule, which was newly designed to insert in-vitro cell samples into the vacuum chamber used for the proton generation. We also report the result of 20-Gy proton irradiation of a human lung cancer cells.
