Position of Photon Creation Simulations
Tantalum, Aluminum Beamstop, and Air
Simulation Parameters
Target Matter: Tantalum
Target Length: 0.0508cm
Beamstop Matter: Aluminum
Beamstop Thickness: 1.27cm
Chamber Matter: Air
Tracker Matter: Air
World Matter: Vacuum
Target physically starts at -84.4cm and ends at -84.3492cm
Beamstop starts at -84.3492cm and ends at -83.0792cm
The tracker starts at -83.0792cm and ends at -3.0792cm
Conclusion
The beamstop is not thick enough to prevent electrons from traveling through to brem off of the air in the tracker.
