Subject:	Helium pressure test on TM2 window and HS water lines at TCS.

I did helium pressure test on TM2 containment box window and HS line at TCS. @ 70psi helium for 3 minutes, HS:2.2XE-7 atm.cc/sec., Window:1.2XE-7 atm.cc/sec. There is no change on HS. But LR on window is bigger than before that was in E -9atm.cc/sec range.
