3.3.9 Toggling Between Real-Time or Live-Time
The MCA component of RADEAGLET is an advanced electronics component that deploys advanced signal
processing algorithms for signal interpretation. The MCA and electronics have a short dead-time after
each pulse where no signal will be seen. This is because the electronics cannot accept a new pulse to be
processed while it is already processing a pulse. The higher the incident count rate, the higher the dead
time. The dead-time accumulates with the measurement time and is dependent on the detector load in
terms of counts per second (cps). Consequently, two acquisition times may be displayed: the real-time,
which is the true time duration of the acquisition and the live-time, which is the acquisition time corrected
by the above defined dead-time. The live time will always be shorter than the real time.
RADEAGLET allows you to review the real-time and live-time by toggling between them. This can be done
by pressing the
LIVE button or the REAL button. The dead-time is the time difference between real-time
and live-time.
