摘要：
In a multi-source radiation generating apparatus including a plurality of combinations of a cathode and a target, an extraction electrode is disposed for a plurality of cathodes in common. When a potential of the extraction electrode is constant, potentials for the cathodes are selectively switched between a cutoff potential which is higher than the potential of the extraction electrode and an emission potential which is lower than the potential of the extraction electrode.
