Obtaining range from bethe-bloch formula

In summary, the conversation discusses the integration in the range formula used in particle physics. The person is seeking help with understanding how the integration is done, and another person suggests using a programming language and the trapezoidal rule. It is also mentioned that the formula involves velocity instead of energy. A reference to a tutorial on beam loss monitoring is provided as well.

While studying particle physics, i saw that the range formula is the integration dE/(dE/dx) but as you know that there are no variable E in the formula. how could that integration be done?

well i think we can do it by ourselves and we must use a programming language and i think the trapezoidal rule would be useful to solve that.

But i could not find out how could that integration be done please help me. thank you

But there is a velocity. From velocity you can get energy.

Look at Equation (1) and Figure 1 in
http://beamdocs.fnal.gov/DocDB/0010/001068/001/A%20tutorial%20on%20beam%20loss%20monitoring.pdf
Eq (1) is the Bethe Bloch energy loss equation for protons. The independent variable is β. The integrated range is obtained by iteration of

dx = dE/[dE/dx]
E=E-dE
x=x+dx
etc.
