AMD installation in ITM chambers - 1st day
Betsy, Slawek, Sebastien
AMD1 and AMD2 have been installed in the ITMX and ITMY test masses. The install went well, and the epoxy curing passed the dynamic test. 24h of curing is required before moving to the next AMDs. Tomorrow, we will continue the work and install AMD3 and AMD4 in both chambers.
Yesterday, I measured particle counts just inside the door to BSC1 just after I exited and while Slawek was still in-chamber. The counts were
1.0um = 200
0.7um = 50
all else under 50.
