Member Function Documentation

◆ CheckParameters()

void BDSBunchHaloFlatSigma::CheckParameters ( )

virtual

Check the parameters for the given bunch distribution and exit if they're problematic or unphysical.

Reimplemented from BDSBunch.

virtual

Each derived class can override this default method of reference position. If S0 > 0 or derived class changes member bool 'curvilinear' z0 will be treated as S and the global z0 be calculated.

◆ SetOptions()

		const G4double	beamlineS = `0`
	)

virtual

Extract and set the relevant options from the beam definition. The distribution type is explicitly required as this function may be used inside a nested bunch distribution. This argument is for the most part ignored, but there's no way to have a default for it. Also, some classes can cover multiple input distributions so need to know which one they're meant to be.
