ズ表面に結露し、腐食が起こる等の問題点があった。In the conventional arrangement of bellows for particle accelerators as described above, the bellows must come into contact with the humid atmosphere, and there are also problems such as dew condensation on the vacuum chamber and the bellows surface due to temperature differences, causing corrosion. There was a point.
この発明は上記のような問題点を解消するためになされ

の腐食をおこし、装置の信頼性を低めることとなる。Next, we will explain how it works. Each part of the zero-particle accelerator is irradiated with radiation, which causes various deterioration phenomena including insulating materials such as Teflon, oil, and rubber. Radiation is
Nitrogen in the atmosphere is decomposed and recombined with enzymes and water vapor, ultimately producing nitric acid in the condensation area on the surface of the metal material. This nitric acid causes crater-like corrosion on the surfaces of the vacuum chamber and bellows, reducing the reliability of the device.
