Unexpected increase in muon range #268
Comments
Hello Piotr! Per default, PROPOSAL builds all interpolation tables up to energy of 1e14 MeV. For energies above, PROPOSAL would extrapolate the tables, which could cause such errors. If you didn't change this upper limit of the interpolation tables in PROPOSAL, I would advise you to do so and check whether this already solves the issue. If you work with a configuration file, you need to add an
Note that the energy is in MeV. You should set the max_node_energy to the highest muon energies that you have in your simulation. |
What are those horizontal stripes in your histogram? |

Thanks @Jean1995 , I indeed have |
Thank you all for swift replies, I think I'm already satisfied with the answers, so I'll close the issue. |
Hi!
I wanted to test what muon range can I expect from
![muon_range](https://user-images.githubusercontent.com/25057504/157468643-4ce2d357-3737-4766-8cb3-145a97e7fb3d.png)
PROPOSAL 6.1.5
, so I shot muons through 100km of sea water to be sure they will stop before exiting. I plotted the reached distance as a function of the initial muon energy:What I found surprising and possibly unphysical is the rise at the highest energies (
~10^11GeV
). Is there any reason why the range slope could increase there? I'd rather expect it to further decrease, if anything.Cheers,
Piotr
