Development of a Positron source using a PbBi converter and a Solenoid
Converter target properties
Definition of Lead Bismuth
1cm diameter target
2 mm thick PbBi
0.5 Tesla solenoid
G4BeamLine and MCNPX
Target thickness optimization
First simple test is to send 1 million, 10 MeV electrons towards a PbBi target and count how many positrons leave the downstream side
The Random number seed is set by Time in G4beamline to use a different set of pseudo random numbers each time it is run
