Summit Inspection #3

A third summit inspection occurred on April 28th (see photos). Like previous inspections, all social distancing and strict safety measures were adhered to, and this trip uncovered no major issues. The team on this visit included Hernán Hererra, Dome technical lead for Rubin Observatory, and a technician from the Italian Dome vendor (EIE), Fabio Serafin, who lives in Chile. They used the mobile crane to access the Dome roof and upper shutter for a full inspection and carried out several maintenance tasks. The following day, another small team went to the summit to inspect and test elements of the Coating Chamber. Next week a summit trip is planned to receive and unload a container with more Dome cladding, which is the last shipment that was in transit when the international restrictions went into effect. Another upcoming planned visit will target electrical maintenance tasks. As winter weather approaches, more visits will likely be necessary to keep everything well maintained.
