 A chip of insulator material was detected below the lower target insulator stand-off (attachment - left picture). The chip may come from the tube heater insulator above (attachment - right picture). The chip will be further investigated when the target is removed.

 The chip came from the lower insulator stand-off on the target assembly (see attachment). After investigating the chipped insulator, it was decided (Pierre, Friedhelm, Anders) not to replace it - as the risk involved may be less than the risk involved in replacing.

Vacuum side

Tuesday, February 16, 2021, 13:42: The gas lines inside have been check. The inlet of the calibrated leak was not tighten properly and hence the large leak observed.  FIXED.

Tuesday, February 16, 2021, 13:42: The only leak remaining INSIDE the vacuum is the one on the FT side which for 200kPa is around 7e-6 atm cc /s. At this pressure, the undesired leak  is leak rate is around 1 %  of the one getting into the source.

Atmosphere side

Tuesday, February 16, 2021, 14:49: Some minor leaks in connection points around  1e-6 atm cc/s. Not much I can do without changing all connection to glands with metal gaskets.

Wednesday, February 17, 2021, 16:53:  The Neon bottle seems to be empty. The leak on the lines were not as bad to have this happened. I suspect when squeezing the bottle I rotated the gauge enough to cause a leak there.

Wednesday, February 17, 2021, 17:00: Using a full nitrogen bottle, I confirmed that rotating the two-stage regulator causes a leak.

Wednesday, February 17, 2021, 18:00: Things look OK now. Water open. No response on vacuum. Will put power.
