 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 |

Monday, June 17, 2024, 07:36, David Wang, ITE, Repair, , , IG1S elbow oring seal and a blabk off cap oring seal beside the elbow were replaced on ITE entrance module top..
|
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. |

Thursday, June 13, 2024, 11:44, David Wang, Conditioning Station, Repair, TM2, , Replaced several o ring seals on TM2 service cap.
|
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. |

Tuesday, June 04, 2024, 11:44, Carla Babcock, South Hot-Cell, Development, , empty LP FEBIAD, investigation of cathode short on empty LP FEBIAD
|
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 |

|
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. |
