|
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 |

|
IG1S elbow o ring seal and a blank off cap o-ring seal beside the elbow were replaced on ITE entrance module top last Friday. IG1s has a higher than
normal reading so i leak checked entrance module top last Thursday and found leaks to 5x E-8 atm.cc/sec leak on one of (or both of )these two o-rings seals.
they are too close to identify exactly on which one was leaking so both o rings were replaced. other air to vacuum seal on entrance module are leak |

|
The annual inspection of the main storage vault will be skipped this year since extensive inspection and testing was performed during the re-alignment
job in May (see this e-log for details: e-log 2584). This included successful testing of the emergency
close mechanism. |

|
The pail handling tool which is used to move 5 gallon pails around the target hall was inspected by A. Newsome. The main tool was checked, but not
the spare as it is currently in a disassembled and unusable state. The tool appears to be in good, working condition. The following items were checked.
Inspect structural integrity of long tube - check for bending, warpage, dents, cracks, rust/corrosion

|
5 gallon spent target pail, lifting long pole and hook assembly load test was done by Rupan, Keyur ,and David. Load in pail 101 lbs, test
time 10 minutes. No deform on pail( pail OD 29.8mm is not changed before and after test. The test passed. Also 50 lbs load test on empty tray transit
frame was done. The frame is good on test. Rupan will have a test report on this job. |

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 |
