To form a suitable metallic coating on the inside of the ceramic chamber, the thickness of the coating is needed to be more than one micron; the material must have higher specific resistivity more than 100 μΩm.There are some materials which specific resistivity is more than 100 μΩm. Most of them are ferro-magnetic metals, thus effects due to the skin depth must be considered. Moreover, methods that make a small surface roughness of a ceramic pipe should be studied.The injection and extraction system of the damping ring, including ceramic chambers, is planning to install in the fall of 1996.
