Chad and I leak checked the HS line at SHC after UCX target installation. On first round helium spray, one of VCR fitting has a leak to E-6 atm.cc/sec range.

Entry  Wednesday, July 22, 2015, 12:13, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Short Findings TM2_Short_July_22.jpg

Pin X was unplugged, short remained, however any slight pressure on the block towards the source tray makes the short go away.

Confirmed clearance between the EE and thr R / U coil lines as well as MSP of coil line.

Camera inspection would seem to indicate that ALL issues stem from a common location...there is a spot where both the pin X waterline and the one of the R / U waterline  contact the heat shield waterline...one on one side of the heat shield line and the other on the other side.
