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.
