Ramping up bias/EE/EL on ITE - will see if the HV cage in the pit can hold 60kV or not.
At around 50kV the bias read current starts to get jumpy. Doesn't look like its an issue for the voltage, but definitely instability increases. |

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. |

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 |

|
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: |

Wednesday, January 10, 2024, 16:51, Carla Babcock, ITE, Standard Operation, TM4, UCx#43, UCx#43 failure
|
To deliver stable beam to RadMol, started heating UCx#43 up again. Target was overheated during initial conditioning in Nov but then ran well for
4 weeks. During the run time, the TGHT voltage jumped around and this was reflected in the ion current, but yields seemed unaffected.
When re-heating it, the TGHT voltage was very unstable and once it got to 440A, it went into voltage limiting mode. We ramped down and it was still |

|
TM4 has seen significant coating of the main standoff insulators and various other components stemming from failure in UCx#43 target. See attached pictures
showing coating on containment box, support frame, main standoff insulators, standoff insulators high voltage shield etc. Note tracking marks on main standoff
insulators. |
