Helium pressure test on TM2 all water circuits is done. 70 psi helium , 10 minutes test time. Leak detector :base leak rate 0.0XE-9 atm.cc/sec, base
pressure 0.0Xe-4torr. No any response on LD during the test. All TM2 water circuit are leak free. |

Tuesday, June 04, 2019, 08:46, David Wang, ITE, Standard Operation, TM2, , ITE water signal interlock check.
|
ITE water signal interlock check is done. Everything is good. Coil 2 circuit no longer used in ITE . PQRU are looped as one circuit fro coil 1
circuit on Module since now. |

|
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. |

Wednesday, August 14, 2019, 08:55, David Wang, ITE, Standard Operation, TM2, , TM2 has been disconnected in ITE.
|
| TM2 has been disconnected in ITE. The bias jumper between U and T was burned out during the last beam time. |

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.
TGHT=0A |

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. |
