The helium pressure test on HS line is done at TCS this morning. I got the same result as last time when we helium pressure it it with first target in April. The leak  rate on this line is 1.8 XE-7atm.cc/sec. So, we know this leak is mostly on the line, but not on the VCR joints connecting the target.  See attachment for last time(April) checking e-log. The leak could be from water block which is same as other lines. I do not think this leak rate will affect the operation.
