TM2 has been moved to CS. All turbo-pumps have been started. The pumping down is good so far. I connected the leak detector to service cap, and
finished the leak check today. The LD base LR:0.0Xe-9atm.cc/sec. 80psi helium were applied to coil1, coil 2. HS and window circuits, each for 2minutes.
No any response has been found on LD. So all water lines are leak tight now. I also sprayed helium to top service cap checking all air to |

Monday, July 29, 2019, 16:17, Carla Babcock, Conditioning Station, Repair, TM4, Dummy LP SIS, New leak on EE water line while testing new In seals
|
Original Problem:
Leaks on the B and D copper blocks, probably due to corrosion between the blocks and the inserts. Final solution, after many tries, was to make
an indium sheet the size of the copper blocks and use that to seal the entire surface. |

Monday, July 08, 2019, 14:56, Carla Babcock, Conditioning Station, Repair, TM4, Dummy HP SIS target, First TM4 conditioning with new source tray
|
Ramping up TM4 with new source tray in. Current condition: new source tray but no water running in lines B, D or window. Multipin on the source tray
grounded but no lines running into the service tray. Vacuum at 1e-6T.
Small sparks at each BIAS voltage increase starting at 30kV. First real spark around 38kV. |

Tuesday, July 09, 2019, 09:15, Carla Babcock, Conditioning Station, Repair, TM4, Dummy HP SIS target, Conditioning TM4 w/ new ST up to 45kV
|
Left TM4 at 40kV overnight with no previous heating. There was only one real spark which turned off TP2 but ops turned it back on. Ramping up again.
Tuesday, July 09, 2019, 09:13 : At 45kV the module is sparking on the top pretty regularly. Turned down and David will remove cover and lock out
target hall. |

David raised the bias to 49.5kV. Module is still sparking mainly on top. Humidity is super high.
Wednesday, July 10, 2019, 09:50 : sitting at 49.7kV for a coupe mins, big spark in vacuum took everything down.
Wednesday, July 10, 2019, 10:16 : Bias at 50kV drawing 0.1mA but looking pretty jumpy. Left it here for ~5 mins then had to turn down bias for |

Tuesday, August 06, 2019, 01:13, Carla Babcock, Conditioning Station, Repair, TM4, Dummy HP SIS target, Checks on EE line leak fix and window line leak (not fixed)
|
TM4 has developed 4 leaks so far:
Line B - seems to be solved with an indium gasket (some testing already done)
Line D - seems to be solved with an indium
gasket (some testing already done)
EE - indium gasket installed, preliminary tests are good
Window cooling line - David found |

Wednesday, February 06, 2013, 14:34, Bevan Moss, Conditioning Station, Development, TM4, CS Test Target #1, 40kV All Common w/o Water Test
|
Today the module was biased to 40kV in the conditioning station. The current draw was 0uA. Sparking started at 27 kV. I have attached the recording
from the strip tool of the vacuum while we were testing. After consulting Pierre if we should take the module to a higher voltage it was decided not to.
The purpose of this test we to check the interaction between the module, cover, new cooling line, EE and EINZEL cables. This test was considered a success |

|
Today while putting the cover on the cord that goes to the controller was bumped. This bent the connector down and caused a vacuum leak. I tried
to tighten the bolts in the hope the leak would go away but it did not and I sheared one of the bolts off. David is inquiring with Edi if the pump can
be repaired or if it needs to be replaced. The good news is that the interlocks work exactly as planned. Upon detecting a leak they shut the turbos down |
