Effect of a Nickel Coating Applied on the Inner Wall of the BPM Supports of LHC

All of the special BPMs, e.g., used for tune and chromaticity measurements in LHC Point 4 will be treated such as to have the standard copper layer on the inside of the beam pipe. Between the stainless steel pipe and the copper layer, a 1 µm nickel coating will be applied. This nickel layer might c...

description All of the special BPMs, e.g., used for tune and chromaticity measurements in LHC Point 4 will be treated such as to have the standard copper layer on the inside of the beam pipe. Between the stainless steel pipe and the copper layer, a 1 µm nickel coating will be applied. This nickel layer might cause a problem if an electrolytic process is used for the plating which could cause a permanent magnetization of the layer similarly as it was observed for LEP. This note gives an estimation of the effect to be expected.
