Tuesday, December 11, 2018, 14:35, Anders Mjos, ITE, Standard Operation, TM4, UC#26, Block move
|
Blocks were moved from ITW to ITE by Frank and David. ITE water flow to dump was re-opened (ITW remains open). A dose badge was installed in the operation
storage area. Dose rates were measured to ~10 mSv/h at 1pm. Beam went off approximately 8:30am (with a short period of 2uA ending at 11am). |

Friday, February 15, 2019, 12:05, David Wang, ITE, Maintenance, TM4, , ITE annual vacuum leak check.
|
Helium pressure test on all water lines: 70psi , 3 minutes. HS has a quick response to 9Xe-9atm.cc/sec for 20 seconds. No response on other lines. All
water lines are good. Air to vacuum leack check on ITE and TM4: TM4 IG1 / Steers side panel has a low E-6 atm.cc/sec leak. The o-ring need to be
changed when TM4 is located at TCS. All other air to vacuum seals are good on both primary and secondary vacuum vessel. |
|
Friday, February 15, 2019, 12:09, David Wang, ITE, Maintenance, TM4, , ITE water system maintenance.
|
The ITE water system maintenance job is done. Changed all paddle wheels and coils on ITE flow sensors. All using water poly-tubes in ITE are replaced
. Started high active water pump, and checked ITE water signals. They are good. No leak has been found on replaced tubes and related fittings.
