Following yesterdays work, Jason and Ryan got new numbers for the alignment of BSC2 this morning, we overshot X by ~.75mm and still needed to rotate RZ by 900mrad. This afternoon, the five of us went to the chamber and made more moves, I think we are very close to done now.

However, I realized when we went back out, that we had collided the -X crossbeam into one of the spring caps on the -X/-Y corner of the chamber. We had just contacted this spring cap, which had already been ground down a tiny bit during the original install. This is on a non-critical part of the spring cap, so I think I will just grind the cap down a little bit more, so we have more like 1mm clearance instead of the .1mm clearance we have now. This will require putting hepi back fully on stops so I can take the load off both springs in this corner and remove the spring cap. This should hopefully be the last major surgery for alignment on the outside. We should be able to start attaching actuators tomorrow, late morning or after lunch.
