Today (2024-07-05), five flasks were loaded in preparation for shipment with the following targets: SiC#43 (Pail 272), SiC#44 (Pail 275), Ta#63 (Pail
266), UC#40 (Pail 278), UC#38 (Pail 274).
The crimped lifting loop has been applied to each pail. The locks have not yet been applied to the flasks at the time of writing this log, but |

Tuesday, July 09, 2024, 16:14, Carla Babcock, ITE, Repair, , , Attempts to reduce ITE:EL trips from HV sparks 8x
|
ITE:EL has been tripping off due to HV sparks. Usually this also trips ITE:Q1/2. These are sitting in side-by-side racks.
The working theory is that HV sparks are returning to ground through the EL and quads, tripping them off. Possibly this is the result of a changed
low impedance ground path. How this change happened could be either something we did during shutdown or the changes we made in TM3, no clear evidence yet. |

An annual electrical and mechanical inspection was performed on the SMP today by Adam Newsome, Travis Cave, Riley Sykes, Maico Dalla Valle, and Jason
Zhang as per Work Permit I2024-07-10-1. The following items were checked:
Check condition of wiring for physical/radiation/UV damage
OK, no signs of significant damage

|
New spring idlers were installed onto rotational chain drive for SHC roof. Operation ran smoothly in both directions to full limit. Chain was noted
to have adequate slack when not on driven side. Periodic checks to confirm operation will continue in the following months to guarantee proper operation. |

|
TiC#7 failed after two weeks of operations - measurements in the electrical room indicated that the negative side of the CHT was broken (35kOhms to the
rest of the target). This was likely due to a large number of proton trips during this target run. At every trip I could see the CHT voltage getting higher
and more unstable. This cahnge in voltage was reflected in the unstable anode current and fluctuating RIB beam intensity, as a direct result of the fluctuating |

|
D. Wang reports that recently the overhead crane has been exhibiting a delayed start (approx. 1 min) when operating in local mode. This issue applies
to the main hoist's up/down functionality only and does not seem to apply to other motion axes. T. Kauss briefly investigated but did not find any obvious
cause. |

|
Update 2024-09-12: C. Fisher confirms this is actually normal behaviour. The Y-axis motion is inhibited when X and Z
are in a certain configuration, which was true when the manipulator was mounted on the wall in storage position. Non-issue. A note about this has been
made in the operator manual. |

|
On 2024-09-12, CNL reported difficulty with lowering Pail 275 from F-308 flask #22 into their tile hole. The four other pails associated with this shipment
were successfully emplaced. It is suspected that the issue was related to a kink in the lowering cable, causing a jam during lowering. This was observed
approximately 1 year ago. |
