|
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.

See attached PDF for details. 60kV Common to the target is low at 343k but I've been told will work. Test will be done again on Friday after it has sat
a few days under vacuum. |

|
Chad and i did a leak check on TM4 heat shield circuit with new NiO#1 target installed. It took about 40 mins(much longer than usual) to pump down the
circuit to leak rate 0.6x E-9atm.cc/sec and 0.0x E-4 torr o leak detector.
All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak tight.Chad sprayed helium on each |

UOx was removed from TM4 yesterday and NiO#1 installed.
Video was taken.
Main stand-off insulators continue to deteriorate. |

Friday, September 07, 2012, 08:54, David Wang, Conditioning Station, Standard Operation, TM4, NiO #1, TM4 NiO #1 target heat shield helium pressure check is done.
|
leak detector pumped down to 0.0xE-9 atm.cc/sec, and 0.0xE-4 torr. All high vacuum gauge readings at CS and TM4 are at low -6 range from 2.2xE-6torr
to 4.2x E-6 torr. Applied 80 psi helium to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit
is leak tight. |

|
TM4 had been connected in ITE. Six turbo pump had been started . thepumpming diwn is very good so far. The water interlock check on ITE and TM4 had been
finished and everything is good.All water signals are strong and constant by visually checking. |
