Anyone has any idea why there is no Compton’s edge in the spectrum. The moving red line representing spectrum by summing flux in xy plane. Code sourse: openmc/Pb_detector_Cs137.ipynb at main · megatharun/openmc · GitHub
Thanking everyone in advance
The Compton edge is a feature that would show up on a pulse height spectrum, which depends on how much energy is deposited in a detector region. Tallying the photon flux as a function of energy tells you how many photons at a certain energy there are. Those are two different, although somewhat related, quantities. At present, OpenMC does not have the ability to calculate pulse height spectra, although such a feature was proposed in pull request #1881.
Thank you so much for the reply. Yes, I misunderstood flux and energy deposited.
