Chad and I finished leak check on HS line with UCx target installed on it.  Base Leak rate:0.0X 10^-9 atm.cc/sec, Base pressure 0.0X 10 ^-4 torr.  Sprayed helium to VCR joints.   No leak has been found . The line will be pressurized with helium at TCS.

 Helium pressure test on TM4 HS line is done at TCS. BLR 0.0XE-9 atm.cc/sec. 70psi helium , 2 minutes. No response. The line is leak free.
