Common functionality to BDSIM integrators.
Integrator that ignores the field and uses the analytical solution to a solenoid.
virtual void Stepper(const G4double y[], const G4double dydx[], const G4double h, G4double yOut[], G4double yErr[])
Calculate the particle motion along step length l in the paraxial approximation.
BDSIntegratorSolenoid()
Private default constructor to enforce use of supplied constructor.
G4double bField
The field strength.
Efficient storage of magnet strengths.
