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 |

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

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.

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

I have compiled the e-mail comments from people involved in High-Power Conditioning of TM3 w/ the new Rev 3 source tray and NiO#2 since Bevan Moss' last

TM#4 with no target has been moved from the south hot cell to the south west silo. |

Wednesday, October 02, 2013, 13:44, Bevan Moss, South Hot-Cell, Standard Operation, TM4, , Right Coil is leaking
|
Today Maico and Travis completed and electrical test to determine the right and left coil on TM4. The left coil is the negative side. From there
Maico pumped on both lines for a leak test. The leak cart pumped down to its lower limits on the left line and there was no response when sprayed with
helium. The right line would not pump below 2.5 x 10^-2 Torr and had a base leak rate of 3.3 x 10^-7 atm*cc/sec (this indicates a massive leak). Without |

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 |

Monday, September 30, 2013, 16:04, Bevan Moss, Conditioning Station, Repair, TM3, NiO#2, Ion gauge filament replacement
|
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. |

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. |

Results of the various electrical checks done on TM#3 while at the hot cell since the 27th of September. View PDF for the details. |

TM4 was move by myself and Grant. Move went smoothly, no hang ups. |

TM#3 with NiO#2 has been move from south hot cell to the conditioning station. |
Friday, September 27, 2013, 12:53, Bevan Moss, Conditioning Station, Standard Operation, TM3, NiO#2, HP TGHT and TBHT conditioning
|
Yesterday TM3 had the TGHT current raised to 160 amps and the TBHT raised to 200 amps. At this power the TGHT showed typical results in that vacuum
was affected and the increased voltage as the target increased in temperature. The tube heater on the other hand did not change voltage or show a change
in vacuum. As a result it is believe there is a short somewhere in the module. I have attached a screen shot of the strip tool and the raw data. |
