|
Starting HV tests on TM2 with 50uA of protons.
Tuesday, August 06, 2019, 03:37 : Ramping up 500V every 2mins or so, couple of sparks, then consistent sparks at 34kV. No vacuum response on IG1
for any sparks, even though the current spikes from around 40uA to 1300uA. Brought it down to 28kV to stop sparking. See a response on the EZL frequently. |

Friday, August 16, 2019, 14:23, Carla Babcock, ITE, Repair, TM2, ZrC#8, TM2 electrical checks in ITE
|
Ramped voltage on TM2 up to 30kV with no problems. Bias current is at 29uA, same as original TM2 bias current (see archiver for ITE June 15th, before
protons) and similar to 31uA right after protons went off on Aug. 6.

Tuesday, September 17, 2019, 07:37, Carla Babcock, ITE, Development, TM2, ZrC#8, end of run HV investigations
|
Ramping up HV to ~30kV, encountered problems and had to drop back to 28kV. No response on IG1 or anything else during sparks. Lots of charging-type behaviour
on the bias current. Protons at 55uA
Tuesday, September 17, 2019, 02:02 : 15 mins with only 1 spark at 30kV so increased the bias |

|
1 Jumpers between 60KV common and FEBIAD lines were connected in an unusual way. This should of had no impact on the ZrC run but would have to
be corrected for any future FEBIAD runs.
2 Feedthrough U was mislabeled (label has been removed) |

|
ZrC#8 has been removed from TM2. Upon removal of the high current tube heater bolts it was noticed that the tube was broken. Also the 9 pin connector
has an arc mark (see pictures attached).
Ta#59 has been installed with new fasteners. High current fasteners torqued to 130 in lbs. |

|
Feibiad gas line for ITE and its adapter fittings for TM2 are tested today by installing them on a dummy water stem. No leak on VCO fitting, adapter
o-rings, and all Swagelock fittings of this assembly. Manual valve on gas line works fine. The positional check on gas line between TM2 and ITW will
be fulfilled next Tuesday during module disconnection. |
