Solenoid Test
100 million e- incident on the target. Created 97997 Positrons. Target is 2 mm thick Lead-Bismuth target, which yields most positrons. 48 mm diameter virtual detector is placed 500mm down of the target to detect e+.
20 cm long solenoid
Solenoid Inner radius=100 mm outer radius=120 mm length=200 mm. Target planced at the center of the solenoid.

The longer the solenoid, the more positrons delivered to the detector.
off center placement
Solenoid Inner radius=100 mm outer radius=120 mm length=400 mm. Target placed 100 mm down of the top of the solenoid. Some positrons went backward (i.e. upstream) to the e- incident direction. I gave up this setup.
