| Outline of Final Research Achievements |
High intensity beams are an inevitable tool to achieve world-class results in high-energy physics. As a result, the ceramic break, which is an essential component in the accelerators, has emitted electromagnetic waves, may destabilize the beams. Recently, the authors theoretically have predicted that the electromagnetic waves can be shielded and the beam can be stabilized by coating the ceramic break with a thin metal film of only 10 nm. In this research, the authors have experimentally demonstrated this prediction and established the basis of the accelerator technology.
