Conditioning
. Ramps the high voltage without heating the cathode. This conditions the HV
components to avoid arcing of electron gun during normal operation. This routine should be run after
each cathode replacement.
Lowpower
. This is the parent state of the parametrization procedure. It is similar to the
“
On
”
state in
that it turns on x-ray generation, but at a lower power suitable for parametrization purposes. Before
being able to enter the “On” state a complete
parametrization must be performed. See Section 5.8
regarding the parametrization procedure.
Align
,
Segment
,
Focus
,
Linefocus
,
Run all
. All these states are sub-states of the parametrization
procedure. See Section 5.8 for more details.
Calibrate
. Measures the spot size and adjusts the electron beam optics to match the spot size settings.
Validate
. Measures the spot size without making any changes.
Deflectorscan
. Performs a raster scan of the deflector x- and y-coils.
5.5.3
State indicators
There are three types of indicators in the GUI that show the state of the system, and if it is in the progress of
changing state.
A)
Requested state
–
dark gray button.
To request a state change, simply click the desired state button.
The clicked button will shift to a darker shade of gray to indicate that the GUI has registered the click.
B)
Change of state in progress
–
yellow button.
A yellow state button indicates which state the system is
currently trying to reach. This is also indicated at the top of the GUI, which shows the name of the
state followed by three dots.
C)
Reached state
–
green button.
A green state button indicates that the system has reached the
requested state.
5.6
User levels
There are three different user levels in the GUI. They are used to control which features are accessible to the
user. The four user levels are:
User
.
The standard login level, in which the user can access the
“
Summary
”
and
“
States
”
tabs. This
allows control of source settings and system states, but not most hardware control parameters.
Admin
.
Most hardware control parameters can be modified.
Service
. All hardware parameters can be modified. It also gives access to the
“
Service
”
tab.
The default user level
is “user”.
Certain operations of the system do, however, require that the user is logged in
at a higher level than the default level. Changing the user level is done in the upper right corner using the drop
down list under the Excillum logotype (see Figure 5-4 above). The
default password is “jxs4944”.
During normal
operation it is recommended to always use the
“
user
”
level.
5.7
Error messages
When an error occurs, it will be
displayed in the “Important messages” region
in the bottom right corner along
with other important server messages. It can also
be reviewed under the “Log”
tab, see Figure 5-5.
The scroll bar can be used view older server entries.
