Detailed Description

Muon-catalyzed fusion model for dd, dt, and tt molecules.

In this model the executor performs the full muon-catalyzed fusion workflow. It forms a muonic d or t atom, samples which muonic molecule will be produced, selects the channel, and calls the appropriate interactor.

The full set of "actions" is as follows, and in this ordering:

• Define muon decay time to compete with the rest of the execution
• Form muonic atom and select its spin
• May execute atom spin flip or atom transfer
• Form muonic molecule and select its spin
• Calculate mean cycle time (time it takes from atom formation to fusion)
• Confirm if fusion happens or the if the muon should decay
• Call appropriate Interactor: Muon decay, or one of the muCF interactors

Note

This is an at-rest model.

Constructor & Destructor Documentation

DTMixMucfModel()

celeritas::DTMixMucfModel::DTMixMucfModel	(	ActionId	id,
		ParticleParams const &	particles,
		MaterialParams const &	materials
	)

Construct from model ID and other necessary data.

Most of the muon-catalyzed fusion data is static throughout the simulation, as it is only material-dependent (DT mixture and temperature). Therefore, most grids can be host-only and used to calculate final values, which are then cached and copied to device. The exception to this is the muon energy CDF grid, needed to sample the final state of the outgoing muon after a muCF interaction.

Todo:

Correctly update ImportProcessClass and ImportModelClass . These operate under the assumption that there is a one-to-one equivalente between Geant4 and Celeritas. But for muCF, everything is done via one process/model/executor in Celeritas, whereas in Geant4 atom formation, spin flip, atom transfer, etc., are are all separate processes.
