Abstract:

Trade-off: porcelain coating vs oxidized polished stainless steel for ACB.
It appears that oxidized polished stainless steel can be
used instead of porcelainized steel with no significant increase of scattered light displacement
noise from the ACB.

Notes and Changes:

Revised the document to correct errors in the scattering ratios and to quantify the conclusions

3-Oct-2011: Peter Fritschel and Dennis Coyne have approved this proposed change to remove all porcelain coatings from the Stray Light Control baffles and beam dumps.
