Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A radiation generating apparatus comprising: a radiation tube including a plurality of cathodes, a plurality of targets, and an extraction electrode, the plurality of cathodes being configured to emit electrons, the plurality of targets being disposed in a one-to-one correspondence with the plurality of cathodes and configured to output radiation in response to being irradiated by the electrons, and the extraction electrode being disposed between the plurali…
