David Wang | ITW | Repair | TM2 | | venting ITW and TM2 with argon. |
A short between TM2 EE and bias is produced yesterday during tube heater ramp up. Alex asked for an argon venting on ITW to see if the problem could be solved by venting and pumping down yesterday. I set up argon venting system in electrical room and started the venting at 8:30 AM this morning. It will take 5 hours to vent the ITW to 760 torr(mechanical gauge reading). The venting system pressure is set as 2 torr. A pressure relieve valve is installed into ITW venting line to prevent station over venting. The argon bottle valve in electrical room will be closed by isac opps after 5 hours venting. |

David Wang | ITW | Standard Operation | TM2 | | ITW primary and secondary vacuum vessel winter shut down leak check. |
TM2 is located in ITW for this leak check. Leak detector is installed between ITW BV2s as before. LD base leak rate 0.0XE-9atm.cc/sec, base pressure 0.0XE-4 Torr. First , I leak checked dump module top flange seal which a small leak was found in last year winter shut down. This time,all ITW turbo-pumps cooling fans are switched off during the check. Lots helium are sprayed around the dump module top flange this time. I did not see any response on LD. The check is repeated 3 times. The results are same. There is no leak has been found on ITW dump module top flange seal at this moment. The further confirming check will be repeated when TM2 is moved back to ITW with dummy Febiad target at the end of this month. The rest check result: 1 small leak(1.2 xE-8 atm.cc/sec) is found on one TM2 blue nylon bottom o-ring. This o-ring will be replaced when module is moved out of ITW. It will be an easy job. Another small leak( 1.1XE-8 atm.cc/sec) is found on exit module 1 service cap top plate to frame o-ring seal. Its location is on east-south side of the exit module 1.This side is close and parallel to exit module 2 west-south side. Vacu- seal sprayer is used to fix this problem. After two times spray, the leak is disappeared. This is not a permanent fix. The big top plate o-ring replacement is a complicate and dose taking job. It need to be well planned. The leak rate is small, and the leak source is close to ITW TP3 so there is no rush to replace the big o-ring on exit 1 service cap top plate at this moment. But, we need to close watching on this issue and have a job plan for this o-ring replacement since it could get worse in the future. There is no leak has been found on big T tank seal this year as well. All other primary and secondary vacuum seals in ITW are good. TM2 water lines helum pressurize will be fulfilled In ITW or at TCS later. I will update this e-log when further test are finished.
2017-01-25: The O-ring on 60KV bias blue nylon stand is replaced at TCS. I leak check it. It is perfectly good now. |

TM2 helium pressure test result at ITW. 70 psi helium 3 minutes on each circuit. LD base LR0.0XE-9atm.cc/sec BP 0.0XE-4torr. ITW IG1 1.22Xe-7 torr, ITW IG1S 1.31XE-7torr, ITW PNG4 2.66XE-6Torr(ITW TP4 off).

All number are getting better comparing to last time check. All ITW vacuum readings are very good. ITW PNG4 was in low E-7 torr range also. At present, it is in low E-6 range due to ITW TP4 switching off. The TM2 water line seals are stable and reliable for 2017 beam run. The same check will be repeated in 2017 mini shut down. |

David Wang | ITW | Maintenance | | | ITW clean up |
ITW has been cleaned up today. All station are vacuum cleaned. I wiped all HV cover and HV area including conductors and insulators. The black foams which are used to wrap around TP back up line are degrading now. I removed most of these foams. Also, Some obsolete water lines are moved our of station. All waste are bagged . they will be surveyed and stored(or disposed) according to radio-active level. |

David Wang | ITW | Repair | | | ITW HALCW 2" return line ball valve seals replacement. |
Leaking seals on ITW HALCW 2" return line ball valve have been replaced. 8 liter waters are drained out for this job. Water are drained into a thick plastic bag. The bag is tie strapped , labeled, and put into a yellow garbage bin in MAA. Water sample is given to RPG. After analyzing, RPG will give instruction on how to deal with it. Since we just refilled NALCW to system before this job, the active level on sample is very low. We may dump them into active sump. After seals change, The system is refilled . I started pump and set everything back to normal configuration. NO leak has been found on new seals. The HALCW system is operating good so far. |

David Wang | ITW | Standard Operation | TM2 | | TM2 ITW |
TM2 was moved and connected in ITW yesterday afternoon. After roughing down, ITW turbo pumps are started. ITW TP4 can not be started to full speed. ISAC ops kept it at low speed mode with less than 1.0A current draw on pump. ITW IG1s shows red as well. I will take a look on them today when beam is off.
