Subject: Drilling between ATF and PSL for fiber 

Eddie told me that the wall in ATF lab is plaster, so he could not anchor the machine thing on the wall. It will be drilled by a hand drill from ATF to PSL.

We tried to move the clean bench in PSL with 4 people, but it wouldn't budge.  So instead of moving the bench, I'll leave it as it is. Since I can cover the wall with Al foil/ plastic / wet sponge around the drilling area so that the dust is confined.



fig1: ATF lab, The hole will be drilled ~3 inches below the pipe.


fig2: PSL lab, there is ~7" space between the wall and the clean bench. I cannot move the clean bench, but I can  cover the wall with something, so I think it should be fine drilling with that.
