keyword=I_beam 20 uA to 30 uA
The vacuum improved significantly, so try to raise I_beam to 30 uA
and thus achieve stable equilibrium. The other option is to run
at 40 uA for one hour, let pressure gauges trip the beam, pump down,
continue 40 uA running, etc.
This is obivously not a nice way to go on until morning, so MCC
will try to figure out what is going on while running at 30 uA.
Beam mis-steering or RF instabilities could be the cause.
