1MeV n-eq fluence

Recording, Visualizing and Persisting Data

Dear all,

I would like to determine the 1 MeV neutron equivalent fluence with Geant4 in a detector - what is the best way of doing that?

I added a scoring mesh to determine the dose in Gy, is there something similar for the 1MeV n-eq fluence?

Thanks in advance!

Dear @mesmeriza ,

I am looking for the same answer.
Did you perhaps manage to measure the 1 MeV neutron equivalent fluence directly with G4?

Thanks,

Hi @preghenella ,

I wrote an email to one of the Geant4 guys after not getting any answers here, and I was told that such a scorer does not exist and I would have to implement one myself. I got the hint that the following scorers would be good starting points:
G4PSDoseDeposit, G4PSFlatSurfaceFlux or G4PSCellFlux scorer. Afterwards, the conversion to 1MeV n-eq fluence is needed.

I ended up measuring the 1MeV n-eq. fluence with Fluka, because it was faster for me (I already had a setup in Fluka and Fluka has this scorer build in).

Hope that helps!
