Note
a)
When switching the console on (starting from the Standby state),
the SEM aperture becomes heated. It may take several (5–10)
minutes before it is at the proper temperature. Do not make any
adjustments during this interval (aperture, source or lens alignment)!
The microscope could become misaligned when the aperture reaches
the operational temperature.
b)
Once you have your user account set up via FEI Account manager
software (see Chapter 3), you can use your name and password to
access both Windows 7 system and the Microscope Control software. Take
note of the Password policy (see above), which helps to protect individual
settings and results.
c)
Usually, the Scios remains on with the vacuum system in operation, but
typically the ion emitter and accelerating voltages for both columns remain
off. The system starts with the setting in use when the Microscope Control
software was closed. This allows quick resumption of daily operation.
