Friedhelm Ames | | | | | | | Problems/Solutions | water tripping in front of HV power supplies |
Found some water tripping in front of the high voltage power supplies rack from the water lines at the ceiling. Plastic sheets have been put on top of the racks and MCR has been informed. |

Anders Mjos | FEBIAD anode end cap test | | | | | | In progress | Water opened - reduced flow heat shield |

Replaced grid containing ring (target side) with new ring. No contact between target and anode measured in lab.
NOTE: While closing up the VCR fittings the tube rotated causing the tube to flatten in a bend. This may reduce water flow on the heat shield circuit. (see attachment)
Wednesday, July 04, 2012, 15:33: Started roughing.
Wednesday, July 04, 2012, 15:57 : Started turbos
Wednesday, July 04, 2012, 16:03: Turbos at speed. Vacuum at 3E-5

Thursday, July 05, 2012, 08:39: Water supply open. Vacuum stable at 5.9E-7. Due to the kink in the heat shield cooling line, flow in the heat shield line is lower than other lines (visually inspecting speed of paddle wheels). |

A short in the anode has developed during the heater ramp up. Increasing the current limit did not cure it. Start heater ramp down to investigate.
|
Wednesday, July 04, 2012: short found between anode and target. probably caused by the target tube coming in contact with the anode due to bending of the tube caused by heating and deformation of the grid retaining ring. see attachements |

Pierre Bricault | | LP-FEBIAD | | | | | In progress | Continue cathode heating |
This morning the pressure was 3.5E-7 T. Current at 275 A is 30nA.
Continue cathode heating to 290 A during meeting.
Start seeing some electron current from the cathode around 275 A. |

Aurelia Laxdal | | LP-FEBIAD | | | | | | Quick check |
Just a quick check at the Test Stand:
1. The system operational ( white out not present ) with TSH:TBHT heating in progress.
2. Started the Archivers: for Source and Optics.
3. Removed bypass on TSH:SV5 since it's not necessary anymore.
4. Currently: TSH:TBHT=107A |
