|
TM3 and UCx#44 ran in ITE but issues with the cyclotron prevented proton beam delivery. Nonetheless, the target was heated and provided stable beam to
TITAN as well as for tuning and some tests.
Results of inspection of TM3 module after run: |

|
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. |

|
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

|
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. |

Monday, June 17, 2024, 17:24, Carla Babcock, ITE, Development, TM3, UCx#44, Status of gas system prototype in ITE
|
A new gas system for FEBIAD operation was installed in ITE to enable us to use a calibrated leak which is attached to the target heat shield. This will
allow us to control the quantity and purity of the gas going into the system, and to switch quickly between gasese and pressures.
The schematic of the system is attached. The use of the ballast container is likely not needed - it was originally included in case we want to |

|
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 |

|
ITW has been behaving badly at higher voltages recently, even without protons on. I conditioned it up to 50kV with heaters off in the TCS and it was
fine. But when I tried to do the same with heaters on in the station, it was quite sparky and it kept tripping the TGHT/TBHT. I went to 49kV where it was
unstable, then lowered to 48kV where it looked fine for 30mins. But even operating at 40kV, it tripped the heaters several times. The TBHT voltage came |

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. |

couple of E-8 to low E-7 atm.cc/sec leak were found on TM2 service cap top air to vacuum o rings. Replaced these leak o ring seals
including o ring on IG1 and steerer service panel,o rings on MSP, EE, D blue nylon and copper feed through, and o ring on a round blank off beside MSP
terminal on second row. |
