|
The failed extraction electrode was inspected in the hot cell this morning by Anders and Chad. The following electrical measurements were taken
EE on target assembly as recieved from TM after online operation. 14 Ohm
EE removed from target assembly and placed on
conductive flat surface. ~1 G-Ohm at 1kV
EE installed back onto target assembly (fasteners not tightened).~ 0.8 G-Ohm at 1 kV

Wednesday, March 02, 2016, 10:04, David Wang, ITW, Standard Operation, TM2, , Leak check on ITW and TM2.
|
Dan and I leak checked TM2 and ITW primary vacuum vessel. It was found a 1X E-7 atm.cc/sec leak on top T flange seal between TM2 and dump module in first
time check. But it is not a repeatable leak. I checked the same spot and around area two more times with increased helium volume.It did not show up again.
The first response could be a helium drift to dry scroll pump. I will check it again later. The primar vacuum vessel on ITW and TM2 are leak free. |

|
SiC#32 has been removed from TM2. Quick inspection shows some troubling discoloration on the water cooled connection blocks of C and D as well as the
left target heater A.
As for the target, both legs are broken and is has the normal "charge up" marks on the 9 pin connector. |

Chad and I finished the first round check on Tm2 water lines. The lines and spots checked are: Target oven + and - (front side braze joints) , Tube
heater+and -(front side braze joints and water blocks), coil2 and coil 1(front side braze joints and area close to water blocks),. No leak has been found
on all above of them. The last, we checked the GE which has the biggest leak so far. The leak detector base leak rate only can get |

TM2 has been helium pressure tested in ITW and TCS. They are both tested with 70psi helium, each circuit for 3minutes.
The leak detector base leak rate: 0.0X E-9 atm.cc/sec, base pressure 0.0 xE-4 torr for both ITW and TCS. The test results are:

|
Chad and I did the helium spray leak check on TM2 GE and MSP water lines at SHC this morning. We confirmed the GE leak on water blocks. We can
not found the MSP leak by using the helium spray since its leak rate in TCS is much smaller than GE leak. The leak check process are as below:

On each water circuit in side the service cap, there are 4 soldering stems which two of them are inside blue nylon insulator and other two are connected
to service tray. Each stem has two soldering spots. See attachment pictures for detail location. I sprayed 15 psi helium on each soldering spots on stems
for 20second on each circuit. I sprayed tons of helium inside each blue nylon.No any leak has been found during the check. The leak detector base leak |
