Constructor Detail

ThinCylMsSim

public ThinCylMsSim(double radLength)

Construct an instance from the number of radiation lengths of the thin cylindrical shell material. The Interactor is constructed with the appropriate number of radiation lengths.

Parameters:

radLength - The thickness of the material in radiation lengths.

ThinCylMsSim

public ThinCylMsSim(ThinCylMs inter)

Construct an instance from a ThinCylMs Interactor.

Parameters:

inter - The ThinCylMs Interactor for this cylindrical shell.

Method Detail

interact

public void interact(VTrack vtrk)

Interact the given track in this cylindrical shell, using the thin material approximation for multiple scattering. Note that the track parameters are modified to simulate the effects of multiple scattering in traversing the cylindrical shell of material.

Specified by:

interact in class SimInteractor

Parameters:

vtrk - The Vrack to scatter.

radLength

public double radLength()

Return the number of radiation lengths of material in this cylindrical shell.

Returns:

The number of radiation lengths.

newCopy

public SimInteractor newCopy()

Make a clone of this object. Note that new copy will have a different random number generator.

Specified by:

newCopy in class SimInteractor

Returns:

A Clone of this instance.

toString

public String toString()

output stream

Overrides:

toString in class RandomGenerator

Returns:

A String representation of this instance.
