clear --  EXT I has stabilized and vacuum improved over the weekend to normal levels
(1.0E-009 mbar)
The FE-GUN settings are operating the GUN cooler than to specs and I will be slowly
increasing EXT I through the next two days. Specifically I will make minor adjustments
to the FE_GUN settings strving to reach past EXT I target values for this particular
tip.
