Electron gun trigger and detector diode signal put into and logic. We want to put the annihilation target in and out, see how it affects the rate.

Annihilation Target     Slit width      Counts  /    Time  (s)     Rate (Hz)
in                      1.00 cm         445     /    199.9         2.23
out                     1.00 cm         545     /    199.9         2.72
in                      1.00 cm         241     /    99.8          2.41
out                     1.00 cm         268     /    99.9          2.68
out                     0.20 cm              /             
in                      0.20 cm              /
