Started ramping up HV, EE and EL together. First small spark at 20.5kV on bias, no reaction in other devices.
Note both BIAS and EL are off in their readbacks. See table below |

After new containment box installation on TM3, Chad and I did a helium spray leak check on two VCR fittings on front side water lines. they are leak
free.
Helium pressurize window water line to 70 psi for 3minutes. No response on leak detector which is 0.0xe-9 atm.cc/sec. |

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 |
