I’m looking for the amount of particles incident on an area per (cm-2) and the energy of those particles.

An example might be a proton beam is incident on a 4cm3 water box with a 2cm3 soft tissue box inside. What neutron fluence is seen on the 2cm3 soft tissue box?

This would be secondary particles being neutrons created.
No, not energy deposited.
It’s essentially an energy spectrum but, instead of numerically quantifying over an entire volume. It’s for an area of cm-2.
Axis will be: (y-axis) neutron fluence (cm-2) vs energy (MeV).

I attached two comparable plots that can be used as examples.



As always thanks and I appreciate all suggestions.

Sincerely, Kurt W. Van Delinder

It really depends on if it's truly just a fluence per area that you're looking for; and it also has a lot to do with the particles and energy range that may be passing through said region of interest. Are you collecting info on primary particles or secondary ones? Are you simply wanting to count the amount of particles and energy that past through a given area, or are you interested in energy deposited in a certain volume? I should be able to help more if I have a better idea of what you're looking at.

All the best,

There is a dose actor to calculate Fluence and a dose actor to calculate the Energy Spectrum but, what is the preferred method to calculate energy fluence (MeV cm-2)?





As always thanks guys and I appreciate all suggestions.
