System chamber pump down went faster than expected. Gun section Ion pumps fired as set point crossed at about 15:00 hours.  Waiting for lower FE-Gun pressures before enabling EHT to protect the gun section from burst in pressure which could contaminate Fe-Gun tip.  Currently system vacuum = 5.5E-006 T.
Gun vacuum = 1.9E-009 T and falling steadily.
Best efforts to return system to users this evening. A replacement turbo is on the plane for Monday delivery.
