Hello Geant4 Users,
I am working on DNAPhysics example. I ran a macro with a single 2 MeV proton beam in a 1cm^(3) of phantom. I noticed only 2 ionisations that occurred at nano meter scale (less than 5nm^(3)). However, with 1 MeV proton beam we see more than those produced from 2 MeV proton beam.
I am not able to analyze and decipher the above phenomena. I was also wondering if there is any threshold on proton energy for this example. Looking forward for your help.
With Regards, Satya.
