|
On April 2, 2024 the wrist on the SE manipulator of the SHC (Serial # 7986) was swapped with a rebuild unit originally from SW position (serial # 8106).
The "new" wrist was a wrist + tong assembled unit with the tong cable being routed if-front of the spacer A-14118 rather then behind as in all
previous replacements (see attached pictures). This change was a result of a discussion with Central Research's senior repair technician who informed us |

|
TM3 new source tray was transferred into SHC on this Tuesday. one hook arm of transfer jig is very close to optic tray tube when engaging the jig on
transfer frame. tube side hook arm should go east side a little bit further to avoid the tube. Also the HS tube top lines to transfer frame
beam bottom distance needs to be watched closely when hooking on the frame.Help from HC window is necessary. By watching on this details, Source tray are |

|
On Wednesday, May 22, 2024 UCx#45 was installed on TM4 in the SHC. Installation was normal other then minor issue with the multipin connector drive screw
not engaging and/or driving properly. This was remedied by loosening the left guide bolt slightly (1/2 turn). After loosening the multipin drove in and
seated correctly (verified by camera). High current fasteners torqued to 130 in lbs. |

|
On May 30 Aaron, Chad and I removed the empty LP FEBIAD target from the SHC into the anteroom to attempt to find out the source of the cathode short
observed online. The behaviour online was that a connection of several hundred ohms was preventing the cathode from being biased. The resistance was still
enough to allow us to run in anode mode, which is what we did. I am not sure where the cathode short came from but there was significant sparking on this |

Carla: Looks like the short on the cathode observed while trying to operate the FEBIAD in cathode-bias mode is still there. Will do investigations
in the hot cell during disassembly. |
