Tuesday, July 07, 2020, 17:43, Carla Babcock, ITE, Development, TM4, , RF tests on new IG-LIS wiring
|
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. |

|
Pump down in the conditioning station started at ~2:40 for rough down. The turbo pumps were turned on at ~3:30 and at 3:52 the pressures were reading as follows:
IMG in the containment box 9.2 x 10^-5 T
IMG in the secondary 2.0 x 10^-3 T
ION in the service cap 4.6 x 10^-5 T
Note that the cross has been installed on the vacuum vessel which now includes a turbo pump and the IMG 100.
Leak check will occur tomorrow. |

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). |
Friday, August 05, 2016, 14:13, Isaac Earle, North Hot-Cell, Development, , , Preparations for NHC Ventilation Test
|
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 ft/min with the lid on the SHC. Using duct ID 7.75", and assuming the average flow velocity is 90% of the flow at duct center, the flow rate was found to be 417cfm. We will attempt to match this figure for the NHC when the ventilation tests are performed. The tests have been scheduled for the maintenance day on Tuesday August 9th.
The anemometer probe and SHC test port plug were checked for contamination: none found. |

Wednesday, May 15, 2013, 10:17, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, Preliminary Results from HV testing
|
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 major spark turned the power supply off. I will be compiling all the the data so it can be compared. Also attached is the archiver data, strip tool data, and RGA data. |

Thursday, October 17, 2013, 17:16, Grant Minor, ITE, Repair, , , Pre-Separator-area (ITE Harp 9) Blocks Replaced 8x
|
The pre-separator-area blocks were replaced today by Bevan and Travis, with Grant present for photos and observation.
Photos are attached of each block replacement.
Some difficulty was encountered in replacing the "Layer #3" blocks (photo 9 attached). An interference occurred between the outside of the west "Layer #3" block and an aluminum channel directly beside the rubber pad that supports the block. The block was initially resting on this channel but slipped off, breaking off some concrete at the edge. See photo 12 attached and notice crumbled concrete inside this channel around the area where the interference occurred. Photo 14 shows the damaged block edge.
It should be noted that when these two blocks are resting flat, there should be a gap between them (i.e. they should NOT be touching as shown in photo 9).

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 happen while current was running in the target. Possible locations are the bottom support leg for the TBHT and the top of the right side target leg, though it was difficult to confirm with the camera.
Otherwise the only thing to note was a blacker-than-usual spot on the inside of the Cu heat shield, downstream in the proton direction.

Thursday, December 01, 2022, 13:45, Carla Babcock, North Hot-Cell, Standard Operation, TM4, C#4, Post irradiation inspection C#4
|
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.
Upon inspection we found the container looked pretty damaged - highly crystallized and distorted. The container had gone banana-shaped, but not in the usual direction. It had curved in the direction of the ion source (see photos). The heat shield and other surrounding components were super clean, no deposits or marks at all. |

|
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 washers. |
Monday, September 24, 2018, 10:21, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Post Irradiation Examination (PIE)
|
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 |
Tuesday, August 23, 2016, 08:05, chad fisher, South Hot-Cell, Maintenance, , , Post Hot Cell Entry Clean-up
|
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.
