Muon Stopping Power, Range and Energy Loss Software
Computational Physics Consultants has developed a C++ Muon Stopping Power and Range Library designed for easy installation in any Unix-like operating system. The library can be embedded in experimental data analysis or simulation codes by calling a handful of functions.
A muon range array is constructed by calculating the electronic stopping power and integrating the radiative stopping powers at selected energies. Fast interpolation methods are then used to calculate the energy loss of a muon given its kinetic energy, the absorber material and thickness. Conversely, the initial kinetic energy of a muon is calculated given its final kinetic energy, the absorber material and thickness. The latter is useful in simulations, whereas the former is useful when correcting for energy losses in experimental data.
Fast integration and interpolation methods are used in order for the library to be useful when correcting for energy losses in event-by-event experimental data and Monte Carlo simulations. The library intends to introduce as little computational overhead as possible.
Demo
The first demo demonstrates the capability of the GetOutgoingEnergy() library function. Input parameters are the ingoing muon energy, the material and its thickness. The output is the outgoing muon energy after energy loss.
The second demo demonstrates the capability of the GetIngoingEnergy() library function. Input parameters are the outgoing muon energy, the material and its thickness. The output is the ingoing muon energy before energy loss.
Downloading
The following package formats are available:
- RPM (RedHat Package Manager)
- DEB (Debian Package Manager)
The packages are downloadable from the user's account upon obtaining a free trial license.
Installation
The RPM package is installed with the command,
on RedHat Linux derivative distributions (Fedora, Oracle Linux).
The DEB package is installed with the command,
on Debian Linux derivative distributions (Debian, Ubuntu).
Both packages include system configuration files to perform updates via the respective package manager tool,
(RedHat)
$ sudo apt upgrade
(Debian)
respectively.
Documentation
The Class Documentation reviews the various classes and public methods of the library. The Muon Library includes Elements (from Z=1 to Z=118), Compounds, Mixtures, and Biological materials.
The details how the muon stopping powers are calculated and integrated is reviewed in the Muon Stopping Power page.
Examples
The Examples page provides example codes that illustrate the programming interface of the library.
