Technologies for Oxygen-Free Copper Electro-Forming and Electro-Polishing developed by Asahi Kinzoku Kogyo Inc., were used to develop "High-Intensity Proton Beam Accelerator", which has contributed to winning a Nobel prize for physics by Japanese scientists.

Required characteristics of High-Intensity Proton Beam Accelerator are as follows:

• To be manufactured in low cost
• High vacuum and excellent accelerating performance (No out gassing)
• High electrical conductivity
• Adhesiveness : 26kg/mm2

To meet these requirements, the manufacturing processes of :

(1) OFC Electro-Forming with thickness of 0.8mm
(2) Electro-Polishing by 40μm

These have been proved to be the most suitable for the Accelerator, in Research & Development by Asahi.
