|
Tested RF from RF driver into new IGLIS wires at ITE. Used 5V, 1MHz (2MHz setting because of internal halving issue).
As expected there was a very slight mismatch visible (original cable ~ 68 Ohms, new cable ~ 53 Ohms).
The matching resistor will be changed and it will be retested. |

Rob Walker has drained the primary side of the conditioning station. It will be flushed, filled and chemically treated. It was desired to
chemically treat the primary side before before but it took so long that sediment was found (things started to grow). |

|
A hole was drilled in the NHC exhaust duct in the east end of the target hall above the hatch to the Ante Room. This will be used for measuring
NHC exhaust flow rate with a thermal anemometer. The hole was tapped and plugged with an NPT tap.
Flow was measured in the existing hole in the SHC exhaust duct in approximately the same location. Flow velocity was measured to be 1415 |

|
Testing on TM3 without a source tray was completed on 13/05.2013. All items were tied to common and the water blocks were left open at the bottom
of the module. They were left with the quick connections at the top. The vacuum was in the low 10^-6T range so this was deemed acceptable. The cooling
lines withing the cage in the target hall were shorted so flow could continue. As you will see from the results a maximum of 44kV was achieved before a |

Did the PIE on UCx#39-IGLIS on Thursday Nov. 2 2022, couple pictures uploaded to docushare. Did not remove the target, just the heat shield cover.
Final electrical check on the module showed a dead short from TGHT/TBHT to HV common, which we did not see online. Seems like it must have occurred
after ramp down? It persisted on the target after we removed it from the module. We couldn't find any obvious contact points, because it seems it did not |

|
Post irradiation inspection of C#4 which was running in TM4/ITE was conducted at the NHC on Nov. 22 2022.
The yields from this target had been dropping and its behaviour was erratic, with the voltages on the tube and target jumping all over the place
sometimes. The ion current on the FCs followed the voltages. We took this to mean the target container was breaking down. |

The target was inspected by Chad and Anders. Photos are available on DocuShare.
It was noticed that the target tube heater terminals had lifted up from the insulator on the target assembly as seen in this Photo.
This has later been detemined to be from the assembly, where additional clearance was required and achieved by installing |

UC#23 experienced short between target and heat shield as it was heated during operation. The inspection of the target after irradiation revealed that
the left target leg was close to the heat shield opening and likely the cause of the short. Marks could be seen on the leg indicating contact. See attached
photo. More photos are available on DocuShare |

Plastic has been removed from the floor and any known active items in the hot cell moved to the south east corner in an attempt to shield the anteroom.
Fields at the aluminum panel were reduced from 66 uSv/h to 58.8uSv\h. No contamination found on walls, floor, tacky mats, or standard aluminum cover. The
aluminum cover with breathable air line hole did have 400 counts on 44-2, 1200 on ludlum. |
