Monday, March 13, 2023, 11:25, Carla Babcock, ITE/ITW, Development, , , 10kOhm resistors installed in ITE/ITW faraday cages
|
On Sept. 14 2022, a 10kOhm 30W resistor was installed in each target station faraday cage, in line with the HV bias supply. This was an effort to reduce
the current draw from the BIAS supply and protect the power supply controls cards which have been repeatedly breaking due to HV sparks (we think). In the
end we still broke cards after the installation, so it doesn't seem to have helped. See below for details on the electrical side: |

10 pins lectrical check result after insulator is installed on water cap C.
pin 14 to 60kv bias has 20 Kohm @250V Megga check. The rest check on ohmmeter and megga @250 are either OLor over 25Mohm which are good. |

Tuesday, February 23, 2021, 09:00, David Wang, Assembly/Bench Test, Maintenance, , , target staion vacuum pumps inspection.
|
Edi and I inspected roughing pump ITM MP1, primary backup pump ITHMP1, and secondary backup pump ITHMP2. We checked oil level and color on all pumps.
Refilled lubricant to ITMMP1. ITHMP1 and MP2 oil level is fine. ITH MP1 oil color is darker than MP2. But, both them are ok still. Shielding block has
been restored after the job. |

Tuesday, October 06, 2015, 13:00, David Wang, ITE, Repair, TM4, , spark on top of TM4 in ITE
|
During the weekend condition The TM4 spark at 30KV without vacuum response. It is confirmed the spark is from the top TM4 this morning.The flexible cables
in a black wire sleeve which is used for febiad X pin connection drooped too close to the TM4 surface plate, and caused the sparking. The problem
is fixed by Anders and David. The cables is put back where it should stay. After test, no sparking on the top. |

Wednesday, June 22, 2022, 09:14, David Wang, South Hot-Cell, Standard Operation, TM2, SiC#42 and SiC#43. , Three of TM2 moves related to SiC#42 to SiC #43 target switching job.
|
Monday morning June 20th: TM2 with SiC # 42 was moved from ITW to NHC.
Monday afternoon: TM2 with no target was moved from NHC to SHC due to 10 pin connector guide pin loose issue. The guide pin has to be moved out
in SHC due to NHC manipulator configuration limit . |

Thursday, January 30, 2020, 10:22, David Wang, ITW, Standard Operation, TM4, , TM4 water lines helium pressure leak check.
|
TM4 internal water lines helium pressure leak check at ITW : 70psi helium 5 minutes on each circuits. Base leak rate 0.0X E-9 atm.cc/sec.
Base pressure 0.0X E-4torr. Only B line(Oven -) has a tiny 1.5Xe-9 atm.cc/sec response on LD during the check . All others all perfect good. |

Thursday, April 22, 2021, 08:41, David Wang, South Hot-Cell, Repair, TM4, , TM4 steerer electical check at SHC and TH.
|
Using SHC electrical test cables routed to to TH, We tested TM4 steerer 4 polarities. At 100v megga test, left, right , up and down to ground
are all OL. TM4 steerer has no short. |
