Typical Histograms

Both DC (see Figure 1 [*] ) and PC (see Figure 2 [*] ) planes show a peak in the center of the detector where the majority of particle tracks pass. Between upstream and downstream (see Figure 3 [*] ) DC planes there is a widening of the cross talk occupancy curve, as the positrons travel through a larger area of the detector due to their helical tracks. The same instrumentation restrictions of the planes are placed on the histograms, as described in Section  [*] .
