Rubin's Surrogate Mirror at the Coating Plant

The campaign for the configuration of the Coating Plant with the surrogate Primary/Tertiary Mirror (M1M3), and the production of coating samples was successfully completed in early February. The samples (protected silver, protected aluminum, and bare aluminum) are now being tested for an aging reflectivity campaign. The M1M3 cell and surrogate are still under the coating plant, and work is resuming inside the cell in preparation for integration of the thermal system.
