Don Jackson brought to my attention some potential HV minimum spark     gap issues with the source tray cooling lines.  It appears:

- The gap between the Ground Electrode cooling lines (ground) and     Heat Shield cooling lines (HV) does not meet the spec of 0.668" MIN

The MK4 optics tray prepared for TM2 (as per ITA6082) had an undersized bore for the banana plug, making insertion of the plug extremely difficult /
impossible.

TM2 was moved and connected in ITW yesterday afternoon. After roughing down, ITW turbo pumps are started. ITW TP4 can not be started to full speed. ISAC
ops kept it at low speed mode with less than 1.0A current draw on pump. ITW IG1s shows red as well. I will take a look on them today when beam is off.

  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:

Tuesday, August 06, 2019, 03:37 : Ramping up 500V every 2mins or so, couple of sparks, then consistent sparks at 34kV. No vacuum response on IG1
for any sparks, even though the current spikes from around 40uA to 1300uA. Brought it down to 28kV to stop sparking. See a response on the EZL frequently.
