Kate, Matt and a wee bit of help from Calum Omc black glass shroud is installed. More to follow ... To do list 1) balance mass 2) beam dump 3) beam diverter 4) laser beam check 5) cables. Please note should look at cable from omc bench. Dan and Matt are going to look at this in am.
So yes the order would like to do things is look at (and fix) the cable interference with black glass shroud (different solutions...will look at what we think is the best one), move the beam diverter/cabling/black glass V dump associated with this, then we can probably go laser hazard to fine tune beam diverter move and also then see if the laser goes through all the apertures in the black glass. If it doesnt I may have to reposition some of the glass pieces (there is some adjustment by design to allow this to happen). Dan and I will start in on this work again this morning. Perhaps laser hazard by lunch, maybe a little after (but dont hold me too that :-))
Then we can put back all the things that were taken off, and then balance the ISI and that should, I think, be it.
Note: Though we had 2 people verify that the EQ stops were all unlocked, now that the glass shroud is on there is no access to the EQ stops. We might want to perhaps think about doing a Transfer Function on the OMC if possible right about now. Just as a sanity check..for me, as thats what I had nightmares about last night that we somehow missed one....
Calum and Kate have lots of good pics on their camera but I will try to post some also today.
And one last thing. Its been a long hard slog by a lot of people to accomplish this. From cleaning the area prior to venting, to door removal (on Wednesday last week..just to get a time line going), to staging all the cleanrooms, cleaning the area and keeping it all fully stocked, to removing payload on the ISI for us to do the work, to people working long hours on the weekend cleaning and staging the glass, to then the three enormously long days this week pre assembling and staging everything and then installing the shroud (where we had a few problems with some parts along the way but nothing we couldnt overcome), to the people who ran looking for parts/equipment at the drop of a hat for us.........basically this couldnt have been done without a lot of help from a lot of people and it was greatly appreciated.
Now for Dan and I to finish this stuff off so we can get about closing up.
Pic........we are so happy its in....now we can sleep :-)
