Mark, Eddy, Tyler and I installed two in-chamber cleaning dust barriers into the south nozzle between BSC3 and BSC2 to provide laser safety in BSC3. The operation went well and was completed before lunch. (Note-I went in first to wipe down the floor and the south bellows convolution. The floor was in good shape as evidenced by the fact that the wipe came away clean except for oxidation. The bellows convolution was not terrible but definitely dirtier than the floor: there were some metal fines and a couple of viton shreds.) 

Randy helped the CPB folks throughout the morning. 

Eddy and Tyler moved a HAM work platform from the east side of HAM1 to HAM2 just before lunch.

The entire crew went down to BSC9 aka ETMX after lunch to work on the dome. There was a bit of a delay while walking plate bolts were removed but the dome was returned to the top of the chamber by the end of the day. I spent some time stowing the tooling etc. that is in the lower level staging area in preparation for moving the cleanroom so that the door can be replaced tomorrow.

Not a bad day's work!
