 The Y-position distribution of the beam shown in Figure ~\ref{sim-DDNT1-y-vs-x} has a sharp drop in the region between -25.8 mm and -27.2 mm that corresponds to the boundary of the target T1.   Figure ~\ref{sim-DDNT1-T1-geo} shows the geometry of the target T1 and the sensitive detector DDNT1.   If the target size was increased, it would eventually intersected the detector DDNT1 at a distance of 25.8 mm from the beam center.   A 1.4 mm wide stripe of low counts is visible on DDNT1 that is a result of the target's thickness of 1.016 mm and the 45 degree angle of intersection.  (<math>1.016 \sqrt{2}=1.44</math>).  The edge of the target does not produce many positrons compared to the face of the target, and as a result you see the stripe.

 As shown in figures ~\ref{sim-DDNT1-theta-vs-y} and ~\ref{sim-DDNT1-theta-vs-y-zoom} (zoomed figure) the positron distribution decrease occures at <math>\theta = 45^o</math>.   Positrons are emitted from both the downstream and upstream side of the target.  As shown in the figure, positrons from the downstream side of the target intersect the detector at angles below 45 degrees while positrons from the upstream side of the target begin to hit the detector at angles beyond 45 degrees.   The 1.4 mm gap represents the transition of positrons between these two extremes.
