icecube.simprod.segments.PropagateMuons module

Tray segments for muon propagation

icecube.simprod.segments.PropagateMuons.PropagateMuons(tray, name, RandomService=None, CylinderRadius=None, CylinderLength=None, SaveState=True, InputMCTreeName='I3MCTree_preMuonProp', OutputMCTreeName='I3MCTree', **kwargs)

Propagate muons.

This segment propagates muons through ice with PROPOSAL; it simulates lepton decays and energy losses due to ionization, bremsstrahlung, photonuclear interactions, and pair production.

Parameters:

  • RandomService (I3RandomService) – Random number generator service

  • CylinderRadius (float) – Radius of the target volume in m (this param is now depricated, use the config file in the detector configuration)

  • CylinderLength (float) – Full height of the target volume in m (this param is now depricated, use the config file in the detector configuration)

  • SaveState (bool) – If set to True, store the state of the supplied RNG.

  • InputMCTree (str) – Name of input I3MCTree frame object

  • OutputMCTree (str) – Name of output I3MCTree frame object

  • **kwargs – Additional keyword arguments are passed to icecube.simprod.segments.make_propagator().

icecube.simprod.segments.PropagateMuons.make_standard_propagators(SplitSubPeVCascades=True, EmitTrackSegments=True, MaxMuons=10, SegmentMaxEnergy=1000000.0000000001, StepWidth=0, PROPOSAL_config_file='/Users/buildbot/actions-runner/_work/icetray/build/PROPOSAL/resources/config_icesim.json')

Set up standard propagators (PROPOSAL for muons and taus, CMC for cascades)

Parameters:

  • SplitSubPeVCascades (bool) – Split cascades into segments above 1 TeV. Otherwise, split only above 1 PeV.

  • EmitTrackSegments (bool) – Emit constant-energy track slices in addition to stochastic losses (similar to the output of I3MuonSlicer)

  • MaxMuons (int) – Maximum Number of muons to be generated by cmc per cascade.

  • SegmentMaxEnergy (double) – Defines the energy large cascades get chunked into after simulating the development with cmc.

  • StepWidth (double) – Distance between individual sub-cascdes in units of radiation length (~36cm). If value is 0 (default), not set, i.e., use module default of 3.

  • PROPOSAL_config_file (str) – Path to PROPOSAL config file

Keyword arguments will be passed to I3PropagatorServicePROPOSAL
