Calculate Muon Energy Loss with Bethe-Bloch Calculator

[Getterdog]

is anyone aware of a Bethe-Bloch calculator for the web? I have a plastic scintillator 1 in thick and am trying to estimate energy loss of cosmic ray produced muons. Thanks

Here's a Github project that you can download and use that's written in python:

https://github.com/theresaobermann/Bethe-Bloch

If you have trouble running the python program, you could also install the miniconda/anaconda python distribution to your machine and use it to install whatever packages you need for the Bethe calculator.

and here's a simpler version also in python:

The Bethe calculator divides the target layer in smaller layers :)
What is more accurate, to use the Bethe calculator or use nist tables?

NIST tables are probably the best source, but if your energy loss in the material is significant you might want to use them in small steps - that is probably what the calculator does.
An even more refined approach would be to take the energy loss distribution into account in small steps of the length as the energy loss is not linear.

I agree.
About the ionization constant may be found here changing the element. There are a lot of materials:
