Big Detector Solid Angle Calculations

MCNPX Simulation
  • 14 MeV neutron source, emitted isotropically ([math]4\pi[/math])
  • Detector placed 1m away from source
    • face of the detector is 15.24cm x 76.2cm, and 3.6cm deep

The solid angle can be found from the number of particles hitting the detector as:
[math]\Delta \Omega = 4\pi*\frac{hits}{hits + misses}[/math]

Results
1E9 Neutrons generated
  • 8618287 neutrons hit the detector
  • [math]\Delta \Omega = 0.108 Sr[/math]
As a test to verify our results
We change the detector size to 1cm by 1cm and used 1E9 neutrons again
  • 32061 neutrons struck the detector
  • [math]\Delta \Omega = 0.0004 Sr[/math]
