|
The water and electrical connections were disconnected today as protons remained off after power interruption during the weekend. Vacuum is still connected
and operating.
The vacuum system are disconnected 2018-07-17. See attachment . |

Friday, September 07, 2018, 10:47, David Wang, ITE, Repair, TM4, UCx24, TM4 TP2 replacement
|
TM4 TP2 could not be started after module was connected back to ITE on Sep 04th. It was replaced with a new pump on Sep 05th. The new pump works
fine. |

Thursday, November 22, 2018, 08:52, Anders Mjos, ITE, Standard Operation, TM4, Ta#57, Closed ITE dump water
|
| Paddle wheel signal was tripping proton beam in ITW. Valved off ITE dump to divert flow to ITW. Field around valve was about 600 uSv/h |
|
Wednesday, November 28, 2018, 07:04, David Wang, ITE, Development, TM4, LpTa 56, New high current flexible cables inspection after LpTa#56 beam run.
|
| Inspected new high current flexible cables during TM4 disconnection. The new cables and adapters work fine. |

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.

Friday, May 17, 2019, 10:47, Travis Cave, ITE, Standard Operation, TM2, Ta#58, Module move
|
| TM#2 with Ta#58 has been moved from the south hot cell to the east target station. |
|
Wednesday, May 22, 2019, 11:50, David Wang, ITE, Standard Operation, TM4, , TM2 has been connected in ITE.
|
TM2 has been connected in ITE. high active water system and vacuum pumps are started. The pumping down on TM2 and ITE is good so far.
See attachment for connection checklist. |
|
Tuesday, June 04, 2019, 08:46, David Wang, ITE, Standard Operation, TM2, , ITE water signal interlock check.
|
ITE water signal interlock check is done. Everything is good. Coil 2 circuit no longer used in ITE . PQRU are looped as one circuit fro coil 1
circuit on Module since now. |
|
Friday, June 14, 2019, 08:15, David Wang, ITE, Standard Operation, TM2, , 5 shielding blocks are moved to ITE.
|
| ITE is configured to take proton beam. |

Thursday, August 08, 2019, 09:33, Carla Babcock, ITE, Development, TM2, Ta#58, TM2 HV conditioning with protons, round 1
|
Starting HV tests on TM2 with 50uA of protons.
Tuesday, August 06, 2019, 03:37 : Ramping up 500V every 2mins or so, couple of sparks, then consistent sparks at 34kV. No vacuum response on IG1
for any sparks, even though the current spikes from around 40uA to 1300uA. Brought it down to 28kV to stop sparking. See a response on the EZL frequently. |
