b) Tray Control Button
Pressing the Tray Control Button will
eject the tray and launch a dialog showing
the tray's progress (1). When the tray is
fully ejected the dialog shows whether it
is fully pushed back (and therefore ready
to be retracted, (2). Once it is ready to be
closed the "Close Tray" button on the
dialog is enabled (3) and pressing that will
close the tray (4). See Figure VI-3 for
screenshots.
c) Run clock
By default the Run Clock displays the amount of time remaining
in the current measurement counting down, clicking the clock will
change the display to time elapsed, counting up (shown in Figure
VI-4).
d) Alphas Counted
This is the number of alpha particles that CounterMeasure has
observed. The number is shown as "Corrected (Observed)". The corrected alpha number takes into
account efficiency losses. See
e) Emissivity Value
This is the current value of the emissivity and its error. At the end of a measurement this value
represents the final emissivity of the sample. The emissivity is calculated in the usual manner (�� = ��/�� ∙
��) where α is the corrected number of alphas, A is the current electrode size, and t is the elapsed time.
f) Status Icons
Status icons report on the status of three auxiliary systems on
the UltraLo-1800: the high voltage bias; the flow controller; and
the tilt sensor. These icons are grey when their status is
appropriate for immediately starting a run and are red when
some change is needed before a run can be started. In addition,
there is an icon to indicate that the software was unable to
