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.
Tantalum, No Beamstop, and Air
Simulation Parameters
Target Matter: Tantalum
Target Length: 0.0508cm
Beamstop Matter: Vacuum
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
Majority of photons are being created in the Tantalum target with some gamma conversion happening in the tracker.
Tantalum, No Beamstop, and Vacuum in every volume but target
Simulation Parameters
Target Matter: Tantalum
Target Length: 0.0508cm
Beamstop Matter: Vacuum
Beamstop Thickness: 1.27cm
Chamber Matter: Air
Tracker Matter: Air
World Matter: Vacuum
Target physically starts at -83.0508cm and ends at -83.0cm
Beamstop starts at -83cm and ends at -81.73cm
The tracker starts at -81.73cm and ends at -1.73cm
Conclusion
All of the photons are being created inside the tantalum, electrons are definitely making it though the tantalum.
In this simulation, I commented out the beamstop instead of setting the matter to vacuum, which explains why the position is shifted by roughly 1cm from the 2 simulations above this one.
