Aluminum Thickness Tests

No Photon Physics

Varying Aluminum beamstop thickness

Tantalum thickness of 0.0508cm

All electron physics turned on

Chamber and Tracker matter is vacuum

Aluminum Thickness	Photon Kinetic Energy Spectrum	Z Position of Photon Creation	Volume of Photon Creation
8.897cm
1.5875cm (5/8")
1.27cm (1/2")
4.4485cm
2.22425cm

Note: Volume 1 = Target, Volume 2 = Beamstop, Volume 3 = Tracker, Volume 4 = Chamber, Volume 5 = else

Conclusion

Without photon physics active and vacuum in the tracker and chamber, I cannot say whether electrons are making it though the target and beamstop.
