|
Maico removed the containment box today allow Travis and I to further test the wiring harness. I disconnected the junction block and Travis and
I repeated the test from yesterday. The all lines except the PNG tested OL. The module was then lowered and the twisted pair connected to the pin that
corresponds to the steerer labeled BTM (it is likely this is not labeled correctly). This testing showed showed that the source of the short found yesterday |

|
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. |

|
NiO#2 has been moved from the south hot cell into spent target storage. It was placed in pail 111 in slot 3C of the storage vault. It was 76.4mSv/hr
upon removal from the south hot cell. |

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.

|
HV testing without the cover continued today. With the EINZEL lens at 30kV the target module was able to achieve 58.7kV. At this voltage any spark
was reeking havoc on the electronics of the TCS. Vacuum gauges signals were occasionally lost, the thermocouple reading would occasionally be lost, turbo
pump would turn off. All of these events caused the interlocks to trip resulting in the power supplies to be turned off. As a result I bypassed majority |

|
HV conditioning of TM2 continued today. At ~53.5kV the module started to spark externally to the HV cover. This is the first time the cover has
been tested to this high of a voltage due to the limitations of the modules. As such for the conditioning station to achieve 60kV while keeping the target
hall open of personnel the cover and cage will need to be modified. To continue with HV testing of TM2 the cover was removed and the target hall locked |

Hi all, The old ITE TP3 pump is moved out and the new pump is in
postion .Since this time I used a new holding ring(1 piece) insead of old 2 pieces holding ring which are thicker than new ring, the old holding
bolts are a little bit too long for the thread holes on the ITE exit 1. I have to find the right length bolts for this new holding ring. The pump |

|
The Glory of TM2 continues 100V at a time. Today I brought the module to 46kV and left it there for 1 hour. During this time there was only 1 spark.
I then continues at up to 53kV. At this voltage the canbus continues to be temperamental when the module sparks. The module is still conditioning and I
will continue more tomorrow. Attached is the dumped data and a screen shot of the conditioning from 46kV to 53kV. |

|
This morning when I went to start HV conditioning CP2 and CP3 both had faults and the temperature of the water was ~27C. I reset the compressors
by flipping the system reset switch. This cleared the fault and allowed the compressors to come one. To the best of my knowledge these faults happen as
a result of compressor fluid pressure too low or high and temperature too low or high and lack of flow. The system cannot determine which one it was that |

|
High voltage testing was started on TM2 with no source tray today. The maximum stable for 1 minute voltage reached was 47.5kV but the module is
still conditioning. With every step up in voltage the current goes up a large amount and slowly bleeds down. Large sparks disrupts the connection of the
CANBUS to the PS which is irritating but the module can be brought up to the equivalent voltage in less than 30 seconds. Attached is a screen shot of most |

|
Firday, November 8 all water blocks (excluding I and K) were blanked off and vacuum leak checked. No responses were found. (First Picture)
I and K could not be blanked off without removal of the water block jig. Also, I dropped one of the blank offs onto the table, so one line could
not be blanked off until a new clean blank off was inserted into the cell. In addition, there was still reminace of a bolt in block Ias it aslo could not |

I leak checked TM2 at conditioning station this morning. All air to vacuum seals on the top of the module are good. All water lines are pressured with
60 psi helium for minutes each. One of the tube heater + water line( 2lines for tube heater + for supply and return) has a huge response on 60 psi helium
pressurizing. The leak rate went from 6.0xE-9atm.cc/sec to maximum leak rate in 5 seconds and I saw a pressure increasing either. when I pressurize the |
