Mulder

(MUon fLuxme’DER)

---

Mulder is a Python package that calculates variations in the flux of atmospheric muons caused by a geometry of interest, e.g. a topography depicted by a Digital Elevation Model (DEM).

The primary component of Mulder is a fluxmeter, which serves as a muons probe. The level of detail of fluxmeters is adjustable, ranging from a rapid continuous approximation, that provides an average flux estimate, to a comprehensive Monte Carlo, that delivers discrete atmospheric muons.

Note

Mulder only simulates the transport of atmospheric muons, taking into account the geometry surrounding the fluxmeter. Mulder does not simulate muon production by cosmic rays. Instead, a reference spectrum of atmospheric muons is used as input, providing the open-sky flux, i.e. the flux in the absence of any ground or other obstacles than the Earth atmosphere.

System of units

Note

Mulder uses the Metre-Kilogram-Second (MKS) system of units (e.g. kg/m³ for a density), except for particles’ kinetic energies which are expressed in GeV.
