Class Documentation

class EMCascade : public Module

Collects and deactivates photons, electrons and positrons. Uses DINT to calculate the EM cascade.

Public Functions

EMCascade()

void setDistanceBinning(double Dmax, int nD)

Change the distance binning

Parameters

• Dmax – maximum distance [m]

• nD – number of distance bins

virtual void process(Candidate *candidate) const

Collect and deactivate photons, electrons and positrons

void save(const std::string &filename)

Save the unpropagated histogram of EM particles

void load(const std::string &filename)

Load the unpropagated histogram of EM particles

void runCascade(const std::string &filename, int IRBFlag = 4, int RadioFlag = 4, double Bfield = 1E-13, double cutCascade = 0)

Calculates the EM cascade with DINT

Parameters

• filename – output filename

• IRBFlag – EBL background 0: high, 1: low, 2: Primack, 4: Stecker’06

• RadioFlag – radio background 0: high, 1: medium, 2: obs, 3: none, 4: Protheroe’96

• Bfield – magnetic field strength [T], default = 1 nG

• cutCascade – a-parameter, see CRPropa 2 paper
