Today in BSC3 - ITMx rebuild

Amidst other in-chamber preps for next week and beyond, Travis and I were able to get into the biergarten cleanroom to separate the main and reaction lower chains of the ITMx.  Both are sitting on their trolly stands.  The ITM03 (old ITMx) was removed from the structure with the ergo arm and secured in it's "cake tin" fro transport back to CIT for forensics studies.  We've prepped the space and equipment in prep to build the laser enclosure.  Next week we'll load the new ITM07 and start setting up IAS equpiment to set the masses up for fiber welding later in the weld.

For the record, we also inspected the reaction chain top mass blade that had the wire broken off yesterday and found it to be in great shape, no visible marks and all other attachment points and clamps in proper order.
