The conditioning station was ramped down overnight and David ramped it back up this morning. Currently trying to get it to sit stable at something higher
than 55kV.

Thursday, January 16, 2025, 14:21, David Wang, Conditioning Station, Standard Operation, TM3, No target, TM3 electrical check at TCS under good vacuum 
|
A complete TM3 electrical check at TCS under good vacuum has been done. Pin 14 to 60KV only has 8K ohm on ohmmeter
check , and it's about 2Kohm @250V Megga. It's low in resistivity. The pin 14 is for thermocouples only so no big concern. The rest things are good.

Wednesday, May 15, 2013, 18:12, Bevan Moss, Conditioning Station, Standard Operation, TM3, No source tray, HV test repeat
|
After discussion with Friedhelm it was decided to continue trying to condition the module today before moving it tomorrow. The voltage was quickly
raised until 40 kV where it was left for ~30 minutes. Sparking was minimal. It was then slowly raised to 44.3 kV it held this voltage for ~8 minutes when
the current started to climb (remained below 200uA as set as a limit in previous tesing). There was also sparking at this point. This continued for ~2.5 |

|
A high voltage test was completed on a target free TM1 in the conditioning station. Only the turbo pumps on the target module were operational
due to phase 2 construction. Testing started at 2:51PM with the following vacuum gauge readings, 1.6 x 10^-6 Diagnostics Box, 7.4 x 10^-7 Service Cap,
2.0 x 10^-6 Containment Box. Voltage was increased ~3kV at a time every minute until 21 kV was reached with a current of 0 uA. Voltage was then increased |

Wednesday, May 15, 2013, 10:17, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, Preliminary Results from HV testing
|
Testing on TM3 without a source tray was completed on 13/05.2013. All items were tied to common and the water blocks were left open at the bottom
of the module. They were left with the quick connections at the top. The vacuum was in the low 10^-6T range so this was deemed acceptable. The cooling
lines withing the cage in the target hall were shorted so flow could continue. As you will see from the results a maximum of 44kV was achieved before a |

Wednesday, May 15, 2013, 16:51, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, Repeat of HV Test
|
The HV test completed on Monday was repeated today over a much longer time period. By taking longer there was slightly less sparking but once again
a maximum voltage of ~44kV was achieved. The resistivity of the water was much higher during this run so the leakage current was less but still in
the >100 uA range. The spark that occurred during the ramp up to the maximum voltage caused the "water resistivity" limit to trip. This was |

Tuesday, May 21, 2013, 11:52, Bevan Moss, Conditioning Station, Standard Operation, TM3, No Source Tray, May 16th Long HV conditioning
|
On May 16th 2013 the module was HV conditioned all day. As a result the maximum stable voltage has been increased to about 47kV (~4kV more than last
test). A maximum voltage of 49kV was achieved but the module was very unstable. Attached is the data from the testing. Note that occasionally the sparking
caused the PS to reset, it was turned back on and the voltage increased back to what it was (or lower) quickly. |

I have fallen behind on the HV testing that has been completed on TM3. Data can be found on docushare in the TM3 Rev 3 folder files are
too large to attach. From the last elog entry the following tests have been completed
July 8 2013 - Long HV conditioning 50kV achieved before sparking caused PS to trip. Was unable to recover to the same voltage |

After the manipulator repair Maico installed the NiO#2 onto the target module. Once connected I completed a leak test on the HS line with
Isaac. The leak testing cart would not pump down originally (something wrong with the cart) but eventually it did start to work. The cart pumped to its |
