Hello all, I’m still new to Geant4 and to Nuclear Phyiscs in general.
Currently I have been attempting to modify or create a physics list that provides a plausible simulation of a 30 MeV proton beam onto Tungsten. I have a physics list that calls for ProtonHPData but the penetration range and produced particles do not seem to be correct.
The physics list I am currently using has:
Hadron Elastic Scattering: G4HadronElasticPhysicsXS
Hadron Inelastic: G4HadronPhysicsQGSP_BIC_ALLHP
Ion Elastic Scattering: G4IonElasticPhysics
Ion Inelastic: G4IonPhysicsXS
Stopping Particles: G4StoppingPhysicsFritofWithBinaryCascade
EM Physics: G4EmStandardPhysics
Decay: G4DecayPhyics
Radioactive Decay: G4RadioactivDecayPhysics
Whenever I use any EM physics, Almost all the process calls are for hIoni instead of hadElastic or protonInelastic.
Also with EM physics enabled there is nearly no penetration because the protons are stopped instantly.
I’ve been struggling for a while to learn what physics would be optimal for a 30 MeV proton beam. I have not come across much information on a proton beam around this energy.
Any suggestions/help or questions would be immensely appreciated, I’m very confused about what physic to use. I am fairly novice in this subject but I would like to become more knowledgeable.
-Sincerely Jason
