Today, Filiberto re-routed the external MC2 (and the 1 shared PR2 cable) from the chamberside test area to the chamber feed thru. From there we spent a little time finding a cable swap and remedying. ( I *think* the switch is related to the callout of "flooring" positions of the cabble connectors in the cable table brackets.) We then set the 6 TOP BOSEMs to 50% OLV. We can now run TFs to kick off SUS Phase 3a testing here. Not entirely sure who will do this - possibly me when I get in midday.
PR2 glass install chamberside was stalled another day as we discovered contamination on the AR surface in many places (smudges as well as FirstContact overspray?). We will need to spend some time drag wiping this tomorrow and and then re-attemp the install.
UFl and SEI should feel free to spend some morning time working on table payload if they want/need. Any MC2 TFs in-progress will be posted or announced.
Hugh and Mitch adding Ballast Masses to HAM3-West.
Thanks Betsy--We added the first layer of 10kg masses (D0901075) at nine locations per D1000907-v1. These are all on the West side to aide in cable routing. Apologies for the interference for some that these will present. These masses are not bolted down but they are accurately placed. We will add the second layer soon to locations deemed out of the way and to others when work needing better access is complete.
Here is a list where the cables were landed for MC2 and PR2 to the feedthrus.
