The right-hand side of this workspace contains three tabs of interest, in which different kinds of
measurements can be viewed:
Figure 8: Measurement viewing tabs
1.
Start-Stop histogram:
View the histograms for up to four pairs of input (or Start) channels
(see Section 6.1.2.1).
2.
Coincidence histogram:
View a modified set of histograms, useful for visually inspecting
coincidence measurements (see Section 6.1.2.2).
3.
Counters:
View the single-detector count rates, or the double, triple or quadruple detection
coincidence rates (see Section 6.1.2.3).
6.1.2.1
Start-Stop histogram
The data displayed in the Start-Stop histogram presents the number of coincident detection events
between two input (or Start) channels as a function of their relative delay, for up to four pairs of
channels. When a detection is registered in the de
signated ‘Start channel’ at time
t
, and a detection
is registered in the ‘Stop channel’ at time
t +
τ
, the number of counts in time bin
τ
increases by one.
