|
After few hickups the TCS was successfuly commissioned.
In the morning, in the middle of the heaters conditioning: 360A/250A for the TGHT/TBHT, the target heater PS tripped and it didn't recover immediately.
I cannot tell if the card is still OK. Before this even, there were few bias current sparks created when the ionized tube was raised above 250A; this also |

|
David Wang and I did the service cap inspection in target hall: see WP I2015-10-06-10.<br>
Signs of sparking were seen underneath 3 insulators: E ("Cavity"), A ("Oven+") and B ("Oven -") at the pair water
lines coming out of the feed-through and going to the HV chase. Specifically one water line of E is very close to the feed-through insulator (2-3mm |

Found spark signs on TM3's containment on the side of the water blocks. They may be OLD or/and NEW sparking signs, but this in not determined at this
moment. Please see picture: first attachment. First and second attachment show the profiles of water block and HV lines. |

Thursday, May 04, 2017, 19:10, Aurelia Laxdal, Conditioning Station, Repair, TM3, no target, TM3 HV test at TCS up to 50kV
|
Today TM3 was conditioned up to 50kV. At 50kV sparking started and to go higher in voltage it needs more conditioning time. Lowered it to 49kV for the
night. |
Friday, May 05, 2017, 19:36, Aurelia Laxdal, Conditioning Station, Repair, TM3, no target, TM3 HV test at TCS up to 65kV

Today TM3 HV conditioning went up to 65kV. I'll leave it here over night. ISAC OPS have instructions to keep an alarm on the HV, and ion gauge and turbo
pump (TP2 tripped 3 times due to sparking). |
Saturday, May 06, 2017, 13:30, Aurelia Laxdal, Conditioning Station, Repair, TM3, no target, TM3 current limiting
|
Today the voltage was raised from 65kV to 65.7kV. After about 10min at this level TM3 started current limiting. TM3 was not sparking when this happened.
ISAC OPS turned it OFF and then tried to ramp it back ON, but could not do it due to the current limiting.
I turned OFF/ON the PS (locally) 20ming ago and and then tried to get it back from the Control Room, but around 4-5kV it started current limiting. |
