TM4 has been connected in ITE. See attachment for connection checklist

  1840   Tuesday, December 11, 2018, 14:35 Anders MjosITEStandard OperationTM4UC#26Block 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).

  1868   Friday, February 15, 2019, 12:05 David WangITEMaintenanceTM4 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.

  1869   Friday, February 15, 2019, 12:09 David WangITEMaintenanceTM4 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.
