Chad and I leak checked coil line(R,U) on TM2 at SHC yesterday. The leak detector was pumped down to 0.0Xe-9 atm.cc/sec before the check. Chad sprayed
helium on the soldering joints connecting the cooling copper lines to the small holding blocks for the coil terminal(R,U). After sprayed helium 2
seconds, I saw the leak rate on LD started to climbed up. The highest leak rate is 4.0xE-8 atm.cc/sec. It is a very positive response. We waited the leak |

so we did this test first. I applied both air and helium to R,U circuit , Chad applied snoop soap on the R,U water blocks.The air and helium pressure was
increased from 40 psi to 90 psi Max step by step.Chad did not see any bubbles on the water blocks during the test. Since we did not find the leak source, |
