Symptom Possible cause Correction procedure
7) – System fails to achieve desired
UHV vacuum pressure.
System not fully baked. Water
vapor limits base pressure.
Bake the system walls,
thereby accelerating the
desorption process. Baking
mobilizes the vapours so
they can be cracked and
pumped by discharge (see
section “BAKEOUT
OPERATION”).
8) – System fails to achieve desired
UHV vacuum pressure.
System not appropriately cleaned
for UHV. Excessive outgassing from
walls limits base pressure.
Clean all components for
UHV and bake the system
again.
