Question Proton Ionisation dE=0 

Forum: Physics List
Date: 13 Jan, 2013
From: Michael Douglass <Michael Douglass>

Hi,

I have a simple single cell model geometry consisting of the nucleus and cytoplasm. I am attempting to use the "Microdosimetry" example physics list to simulate standard proton processes in the cytoplasm and DNA processes in the nucleus. I have configured my geometry so that the cytoplasm is part of the "defaultRegionFortheWorld" region and I have created a new region around the nucleus called "NucleusReg". I have allocated DNA processes to the "NucleusReg" region and standard physics to the world region. (See attached physics list). The nucleus is composed of water and the cytoplasm is composed of a custom material. I have attached the output from a single proton track (attached). When the proton transitions from the nucleus to the cytoplasm, there are many hIoni processes but none of them deposit any energy. This is clearly not working properley.

Can anyone suggest a reason for this error?

Thank you

Regards

Michael Douglass
