| Research Abstract |
The charge stripper foil is irradiated by a high-energy, high-current beam, which causes an outbreak of pinholes and shrinkage in the foil. High-resolution observation devices are necessary to the study the development of the damage and the growth of the pinholes in the foils. We devised an ultra-high-resolution observation system using the principle of the telescope within a high-radiation aria. This system can withstand high radiation aria, it has an ultra-high resolution of 8.33 μm at a distance of 8 m.
