|
Travis and I completed an electrical check on the wiring harness for the devices on the ground plane. All lines passed 500V with the megger except
for PNG and the BTM steerer. Those devices had a short to ground. of ~1.4ohm. |

Further attempts to localize the leak were unsucessful. The circuit was pressurized with 60 psi air and snoop solution was applied to both the braze
joints and the mating surface between the two halfs of the water blocks. Unfortunately, no visible bubbles could be dectected.
This was reported to Grant and Pierre and it was decided to continue with removing one of the vcr gaskets from the optics cooling lines (on the |

On Monday, March 11 the containment box was removed from TM4 and a vacuum leak check preformed in an attempt to locate the leak in the ground electrode
circuit.
Following Pierre's work plain helium was sprayed was the highest joint accessible towards the lowest. |

|
The containment box has been re-installed and the window waterlines reconnected and leak checked.
The window lines did pass the leak check, however the leak dectoctor did not pump down past 5.8 x 10-9.
The front cover has also been reinstalled. |

Tuesday, April 23, 2013, 15:52, Bevan Moss, Conditioning Station, Standard Operation, TM3, N/A, Further HV Testing
|
Further HV testing was completed today from ~2:00 until 3:00. The resistivity of the water was 11.7 - 12.7 Mohm. The EE was turned on to 1500 V
and had a leakage current of 1.465 mA with a inline and ballast resister of 20 kohm and 1 Mohm respectively. In addition to this all of the CB were turned
on to 500V. The voltage on the source tray with all bias items tied together and the voltage was then raised to 30kV in 5kV steps. It was then raised until |

|
Aurelia and I investigated this current limit issue May 8th. First, By separating TM3 from TCS. we found the problem is on TCS side. We did a Megga
test on TM3 as well. TM3 is good at 1KV megga test. After that, The insulators between TCS to ground is test. they are good which could hold 1G ohm at
1000V megga test. So the problem should be on power supply side including power supply itself ,cables and transformer. Later, Tom and John found |

David W. has installed two SST Proteus flow meters, model OV7006FTA32, on ITW Heat Shield and Coil. The flow meters are connected to a power supply and
a data logger in the electrical room.
The Heat Shield flow meter has SN 00278112 and is on the Black wire pairs and connected to CH3 & CH4 on the logger. |

Ramping up TM4 with new source tray in. Current condition: new source tray but no water running in lines B, D or window. Multipin on the source tray
grounded but no lines running into the service tray. Vacuum at 1e-6T.
Small sparks at each BIAS voltage increase starting at 30kV. First real spark around 38kV. |
