|
R. Kuramoto and A. Laxdal measured the distance from the 2A tunnel to the tank flange of ITE. The new fabricated beam pipe with bellows was used to gauge
the distance to the tank flange; The flange face of the beam tube was butted up to the tank flange and the beam tube was marked at the plane of the wall.
A metal rod was used to gauge the distance to the tank face using the same method. |

|
A hydraulic leak was found on the manipulator install and repair cart, upon further investigation the cause was a faulty cylinder. Once the
cylinder was removed and disassembled the inner bore was found to be scored beyond repair. Another point of interest was that the rod was painted to the
point that when retracted it compromised the rod seal causing the cylinder to leak. attached are photos outlining the issues. new cylinders are being sourced |

|
There is an air to vacuum leak on TM2 service cap side panel which we moved out during the TM2 wiring job. The CS pumps are stopped now. The CS will
be vented soon. The seal on this panel has to been changed.
2016-06-30. The o-ring seal on this panel(PNG1 and steerers) is replaced and leak checked. No leak now. |

|
I leak checked TM2 at CS this afternoon which including air to vacuum check on service cap and helium pressure test on water lines. There is a
small leak on water line R ,U (COIL1) during the helium pressure test.. Below 20 psi helium, there is no leak on it. But , once the helium pressure is
increased over 20 psi, it showed up on Leak Detector. At 60 psi helium, the leak rate is 9.4xE-9 atm.cc/sec. For detail information, See attachment. |

Chad and I leak checked the heat shield circuit after sic 27 target installed. It took 20minutes to pump down the circuit to the leak
detector bottom scales. The leak detector is calibrated today,and all the vacuum lines and connections are leak checked by spraying helium. Chad sprayed
helium to each vc fittings for 2 seconds. There is no any response on leak detector . The test repeated one time and the result is same. Chad flushed |

Chad and I
leak checked the heat shield circuit after uc#3target installed. It took 5minutes to pump down the circuit to the leak detector bottom scales. All

|
I did a leak check on conditioning station vacuum system today.The vacuum system had been roughed over night . This morning before the leak check,the
convectron gauge reading on emittance box is 20m torr which is reasonable. I hooked the leak detector to system (without turbo pump on)
. The leak detector showed base LR 6.3xE-8 atm.cc/sec. At this base LR, I found 2 leaks up to low E -6range on that cross tube flange to small turbo pump, |

|
Chad and I did a leak check on TM1 Nb5 target heat shield circuit. The leak detector was connected to heat shield circuit.The pumping down of the
circuit is very smooth.Base leak rate is 0.0xE-9atm.cc/sec,and the base pressure is 0.0xE-4 torr. Chad checked the helium flow downstairs .He sprayed helium
to both up and down VCR joints 2seconds each time. There is no any response on leak detector(30 seconds waiting time). Both joints did the same test twice, |

Chad and I did a leak check on heat shield circuit after target is installed on TM1.The leak detector pumping down is smooth. The base leak rate is 0.0xE-9
atm.cc/sec. The base pressure is 0.0xE-4torr. Chad checked helium flow downstairs and sprayed helium to each joints for 2 seconds.The first joints is good
and there is no any response on leak detector.we double checked it again and got the same result. On the second joint, Chad sprayed helium 2second. After |

Chad and i did a leak check on TM1 heat shield circuit with new Nb#7 target installed. It took about 5 mins pump down the circuit to leak rate 0.0x
E-9atm.cc/sec and 0.0x E-4 torr on leak detector.
All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak tight. Chad sprayed helium on |

|
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 |

2018-02-27: Anders and I finished leak check on ITE primary and second vacuum vessel seals. LD connected to ITE BV2 valves between. LD, Base Leak rate
1.2 xE-9atm.cc/sec, base pressure 0.0XE-4torr. There is a leak has been found on TM4 service cap KF25 blank off. The o-ring on the blank off will be changed
later. It is an easy fix . Other seals are good. The big T tank seal on secondary vessel is leak checked as well. It is still fine. Helium pressure |

|
On May 30 Aaron, Chad and I removed the empty LP FEBIAD target from the SHC into the anteroom to attempt to find out the source of the cathode short
observed online. The behaviour online was that a connection of several hundred ohms was preventing the cathode from being biased. The resistance was still
enough to allow us to run in anode mode, which is what we did. I am not sure where the cathode short came from but there was significant sparking on this |
