 Tuesday, September 17, 2019, 07:37, Carla Babcock, ITE, Development, TM2, ZrC#8, end of run HV investigations 
|
Ramping up HV to ~30kV, encountered problems and had to drop back to 28kV. No response on IG1 or anything else during sparks. Lots of charging-type behaviour
on the bias current. Protons at 55uA
Tuesday, September 17, 2019, 02:02 : 15 mins with only 1 spark at 30kV so increased the bias |

Tuesday, October 01, 2019, 09:23, Don Jackson, ITE, Maintenance, TM2, ZrC #8, 60KV Common Connections
|
1 Jumpers between 60KV common and FEBIAD lines were connected in an unusual way. This should of had no impact on the ZrC run but would have to
be corrected for any future FEBIAD runs.
2 Feedthrough U was mislabeled (label has been removed) |

Friday, November 29, 2019, 13:10, David Wang, ITE, Standard Operation, TM2, SiC 39# febiad, TM2 SiC#39 connection check list.
|
| TM2 has been connected in ITE. All turbo-pumps are started. |

Friday, January 10, 2020, 10:26, David Wang, ITE, Standard Operation, , , ITE water signal inerlock check.
|
| ITE water signal interlock check is done. Everything is good. It is a annual check we do in winter shut down time. |
|
Wednesday, January 29, 2020, 12:37, David Wang, ITE, Standard Operation, TM2, , ITE primary/secondary vacuum vessel leak check.
|
Leak check on ITE vacuum vessel is done. LD base leak rate 0.0XE-9atm.cc/sec. base pressure 0.0Xe-4torr. Sprayed helium on all ITE primary and secondary
vacuum vessel seals(including TM2). No leak . Also,70psi helium pressurized TM2 waterlines inside the module for each circuit 3 minutes. No leak
on all operating TM2 waterlines. |

Friday, February 28, 2020, 09:36, David Wang, ITE, Repair, , , Entrance module TP1S broken piesces clean up.
|
Using the camera, Frank and I inspected the broken blades in vacuum duct bending section. We are pretty sure some of the broken parts are
fallen into bottom of entrance module and vacuum vessel since the broken pars are over on the edge of bending section. The blades rotated at high
speed. Basically, They were shoot to the duct opening when they were broken from the pump. Frank and I carefully swiped all broken parts from the |

Wednesday, March 04, 2020, 11:52, David Wang, ITE, Standard Operation, , , ITE HV test without module
|
ITE bias test is done to 48KV. No spark. We can not raise bias above 48KV. It looks like we have a current limit issue on control system when testing
above 48KV. John Cow checked current limit on PS locally. It is set to 8mA which is much higher than the test current. Isac operator issued an e-fault
to control group. |

Wednesday, March 11, 2020, 10:39, Travis Cave, ITE, Maintenance, , , Entrance module move
|
| The entrance module has been moved to the east station to the south hot cell for inspection from the turbo pump explosion. |
|
Thursday, March 12, 2020, 13:48, David Wang, ITE, Repair, , , Entrance module TP1S broken piesces clean up.
|
The broken pieces in ITE entrance vacuum pit are vacuumed out. At SHC, There are 4 pieces on module collimator block top, wiring scanner
top. Chad removed them out at SHC. Electrical check at module top is done by diagnostics group. Everything works fine. |
|
Friday, March 13, 2020, 09:24, Travis Cave, ITE, Standard Operation, , , Entrance module move
|
| The east entrance module has been moved from the south hot cell back to the east target station. |
|
Tuesday, March 17, 2020, 11:42, Travis Cave, ITE, Standard Operation, TM4, P to N target, Module move
|
| TM#4 with the P to N target has been moved from the south hot cell to the east target station. |
|
Tuesday, March 17, 2020, 14:59, David Wang, ITE, Development, TM4, P2N, ITE turbopumps are started.
|
| They work fine. Current draw on all pumps are normal. I asked operator to switch on IG1 , IG1S and PNG4. |
|

Wednesday, May 20, 2020, 13:19, David Wang, ITE, Maintenance, , , Restart of ITE turbo pumps.
|
PLC6 drop out in weekend caused the ITH MP1 and MP1s stopped. ITE turbo pumps were running still after that. Without back up pump, TPs started to trip
off later . I found TP1,TP3, and TP4 were tripped off this morning. And , The rest pumps ran with high current draw. Jon Aoki restarted
back up pumps and ITE turbo pumps. The ITE vacuum system works fine now. |
|
Monday, June 01, 2020, 12:46, David Wang, ITE, Maintenance, , , ITH:CM6 ,CM6S and ITM:CM3 calibration.
|
Edi calibrated ITH:CM6, CM6S and ITM:CM3. By the same time, ITH:MP1 and MP2 lubricate oil level are checked. Everything looks fine. No oil
leak on both pumps. |
