| The roughing pump for TCS was started at ~3:00 and the turbo's turned on at ~4:00. This is the minimum time for the module to pump down. |

The filament on IG1 for TM3 was replaced by myself and Edi. The old filament did not appear to be damaged but the controller claimed it was. The
current gauge on TM3 is a single filament, ideally it would be upgraded to a double. |

Yesterday the TBHT was ramped to 250 amp and the TGHT was ramped to 440 amps. Attached is the data from that run the strip tool that had this screen
shot crashed but it can be recreated with the data. The TBHT ps was not reading back accurate results as such there are large steps in current or voltage
or some instability for no apparent reason. In addition to this the ramping program is still not working so the ramping was a very manual process. The |

Here is the change in the TCS vacuum after heaters were turned off earlier today:

high voltage conditioning was carried out over the day up to 24 kV. i will leave it at 20 kV over night. Current is at 22 micro Amps, heaters off.
vacuum: IG1 7.7e-7

The high voltage was sparking several times during the night. It may be correlated with the cycling of the cooling water temperature and conductance.

Sunday, October 06, 2013, 17:08, Friedhelm Ames, Conditioning Station, Development, TM3, NiO#2, trip of all power supplies
|
All power supplies tripped on high conductivity of the cooling water < 5 MOhm, It is not clear if this was caused by a spark or vice versa. According
to the strip tool for this signal the resistance of the water went up. There might be a fault in this signal. I do not have permission to force this signal
so I keep the heaters off. We should revisit the interlock conditions, this signal should not be included in the interlocks for the heaters. Both target |

Thursday, November 21, 2013, 12:12, Anders Mjos, South Hot-Cell, Standard Operation, TM3, NiO#2, End of beam target inspection - ANODE does not hold 250V
|
The target was inspected by Chad and Anders in the Hot Cell. Electrical megger tests were done during the assembly. It was found that Insulators No 3
(ITD0311) and No 2 (ITD0310) failed to hold voltage after the run.
